    I'm a LADA diabetic and up until a few months ago I was on 2000 mg metformin,insulin and linigliptin.

    At the same time I was having symptoms of neuropathy such as tingling in arms and feet and even shooting pains in toes. I had test done and my diabetic levels were 43 which I'm told this was normal and then had an mri and electrical tests with a neurologist an d everything came back normal no nerve damage.
    My gp suggested I was over medicated and took me off the met and linigliptin and I was insulin only. Well these symptoms started to go. However I have now struggled with getting my levels down and I don't want to take more insulin so I discussed with my specialist to try just 1000 mg of met with 10 units of novomix in the morning and evening.

    Well a few weeks down the line I am getting the tingling and pains again. I am wondering if it is the metformin.

    Has anyone else experienced this.

    I got pins and needles in my hand and memory problems with metformin. Metformin can lead to vitamin B12 deficiency which can result in neuropathy. I have now stopped taking metformin.

    I was given Metformin when the GP said that I have diabetes. I had no problems before I started but on Metformin I was feeling sick and my feet started feeling as if I was stepping on cotton wool. I was then put on the slow release Metformin 1500 to 2000mg a day and Gliclazide which I took before meals. A few days after I was getting pain in my ankles and feet. It felt as if there were worms going through my blood vessels or being cut with razors and it was extremely painful. This sensation stopped when I stopped Metformin a few weeks later. They say these problems are supposed to go away but I was getting tingling in my extremities and I started not being able to feel my feet and lower legs. The consultant diagnosed a neuropathy in them. I started feeling my feet and upper legs when I stopped the Gliclazide. I had quite a severe reaction to Gliclazide. I tried a little metformin a few weeks after stopping the gliclazide but the sensations returned immediately. I remembered that there was nothing wrong before I started the drugs even though my fasting blood was at 17 mmol/l and HbA1c was extremely high. Before I started the drugs I had no problems with my feet. Thankfully the well feeling in my feet has returned after stopping these drugs about six weeks ago.

    Hello I was also given Metformin but had constantly to run to the loo and sometimes did not make it. I stopped going out it was so bad and eventually was taken off it and am now taking 100mg Sitagliptine. I am now experiencing terrible shooting pains in my feet and they feel on fire. Is this another side effect do you think? What medication do you take now?

    I stopped taking metformin and now have no diabetes medication. Despite that, I have managed to reduce my HbA1C blood sugars from 99 to 43. I did this my eating a LCHF diet ... see https://www.dietdoctor.com/low-carb for some ideas of what to eat on a low carb diet. I also did some intermittent fasting. Check out the videos by Jason Fung on the benefits of intermittent fasting for people with type 2 diabetes.

    You need to get a blood glucose meter to find out which foods to avoid. Typically you need to cut out breakfast cereals, bread, potatoes rice and pasta. Also avoid fruit juice and fruit like bananas and grapes. You should find you blood sugars decrease if you avoid high carb foods. You glucose meter will give you the confidence that you are making progress.

    Initially my blood glucose was about 13 at diagnosis. After five weeks of cutting out food high in sugar it had decreased to 9.8 and I then got a meter. I slowly reduced high carb foods and my fasting blood glucose numbers reduced to about 6.5 over the next few weeks.

    Drugs like metformin don’t lower blood glucose by much. Diet is a lot more effective, but you need to be doing something to lower blood glucose or otherwise you may get complications like blindness or painful neuropathy.

    Hi, it looks like you are having a bad reaction to it to me. They say that the side effect will disappear if you take it for long enough but my symptoms are way over the top. One should not have to experience so much pain and it means that there is something wrong. I reacted badly to co-promoxamol (distelgesic) which is now a banned drug. There was something on the news about metformin which is a wonder drug and they say they want to prescribe this to prevent aging. I am told that supermodels also use it to help them lose weight. It helped me lose weight because it was making me feel sick. I could not take the metformin or the gliclazide and I need insulin but was allergic to the one they tested on me. So I just put myself on an ultra low carb diet. I try to aim for zero carbs but it appears to be impossible so I keep them under 20g a day. I am not getting the safe range of blood sugars as my fasting BG is 8 to 10 but this is amazingly low now as it was initially 17mmol/l when I was first diagnosed. If one does not react so badly to the drugs it is best to have them as it rests your pancreas and lets it regenerate if that is possible. Thumbs up to @ArtofFlowers and the low carb diet. I have had to cut out all carbs and starchy foods but it all depends on how much your body can deal with to be able to achieve normal BG.I found that coconut oil can reduce my blood sugar more than Metformin.

    Thank you for your replies
    Well I stop taking the met a few days ago and guess what? The pains and feelings have started to stop.
    Mmm I'm guessing it is that that is causing it. I remember I took met .any years ago for pcos and never experienced this .

    Rosieroo - I had a similar problem after taking Metformin for the first two years of Type 2 diagnosis and treatment. However, being a medical doctor I started to do research on it and discovered that Metformin was depleting my Vitamin B12 and causing neuropathy.

    I went to Holland & Barrett Health Store and bought Vitamin B complex and B12 (25mcg) combined in one tablet. I take one tablet daily in the morning up till now.

    My neuropathy disappeared completely within one month. I hope it works for you too.

    My diabetes is well-controlled. Despite taking Metformin for 19 years after the neuropathy I initially suffered, the Vit B complex and Vitamin B12 has kept neuropathy away.

    sorry to rain on the topic :(

    can you give us a span of what blood sugars are like with and without the medications you say are causing the issues ?if you are running totally spot on without the additional meds -- then happily ditch them

    if howerver the BG's are high without all the meds then perhaps they become a necessary evil ..........
    further discussion with doctor sounds an outcome...


    i am liking what @achike said on this subject very much
    sometimes it is something we are not looking at that is the issue.

    Hello himtoo! I have never experimented on stopping my anti-diabetic medications in my 21 years as a diabetic because they stabilised my blood sugar which was high at diagnosis.

    I take them religiously but I had to stop Pioglitazone 45mg daily 5 months ago when I developed some adverse effects which has now cleared.

    I did wonder if it was b12 however I have had regular blood tests and my b12 is fine. Also I was only on the met for a few weeks again and the symptoms came back could I get depleted that quickly.
    Himtoo- I went back on the metformin because the insulin alone was not enough and I didn't want to inject more insulin if I could control with a little metformin. I am back in a couple of weeks to see the specialist so I will discuss.
    I have to admit the last week or so I have not be good with the food being Christmas. I have rained it back again and started to eat better again.

    I am annoyed that I was not prescribed B12 when they gave me metformin. It appears to be mandatory when prescribing met in the US from what I read. They also prescribe something else such as coenzyme QA with this. However it should help to also take vit B complex. My GP told me that they cant prescribe anything more than D3.
    Anyway the metformin had no impact on my blood sugar and the neuropathy did not stop when I stopped this as I was still taking gliclazide. Though I had then started taking B complex with the gliclazide this continued to make my neuropathy worse. It got to my heart muscle and head. I would have gone blind within a month or two of taking these drugs if I had not stopped them. It does appear that these drugs are causing and accelerating the neuropathies. Anyway it is easy enough to do the diet I just have to reduce the proteins. .

    I've just tried L-Arginine for neuropathy since yesterday, it works immediately and WOW. I am able to feel my legs again and no pain.

    Old topic just wanted to give my experience if helps anyone. Diagnosed type 2, 7.8 and put on metformin 500mg. Everything good till a little over a week. Pain in toes and balls of feet. Had never had any feet issues before then. Got worse as days went by, progressed to my legs/thighs, accompanied by intense burning in my feet, numbness with tingling and shooting pains. Could only sleep for an hour at a time. Would wake up and have to massage and lather lidocaine to get any brief relief. Couple more days shoulder joint pain, burning arm muscles with hardly any exertion, numbness tingling in fingers and fatigue. As this was happening I was figuring I had gone undiagnosed for to long and was suffering from nerve damage which gp also said. Decided to stop all meds and supplements except alpha lipoic. Was taking lisinopril, B, D, C, Calcium and krill oil. Three days later I was 60% back to normal. I could actually walk and get sleep. Couple more days almost back to normal. I started off just with the metformin since my BP wasn’t bad. After a week all the 1st symptoms were back and couldnt hardly walk again. So doctor declared me allergic and intolerant to metformin. Do not know if it was due to vitamin b deficiency or not since that usually takes a long time they said and wasn’t tested. Anyways good luck to everyone I don’t wish this type of pain on anyone and have new found respect for those who go through it.
