Diabetic Neuropathy - Burning Feet and pain - Help Required

I have had type 1 diabetes for 13 years now and my control has not always been so good until about 2-3 years ago when I first got a complication with my eyes.
I then took my doctors advice and went on a pump.
I found the pump easier at first because Id attach the pod and press a few buttons when I needed a bolus for food. After being on the pump for a while, I soon realised that it is actually alot harder because in order for it to work effectively, you have to constantly fine tine it. Being a single male, i also had an issue with the pod constantly attached and when I went to the gym etc, getting showered or changed, it was always there and I found it to be a bit of a passion killer!

I then got the Freestyle Libre and after about 3 weeks of using the Libre, I noticed that my BG graph was very unstable. My pattern looked like an ECG. It would just be troughs and peaks throughout the day.
I then decided to try out MDI again so I went back to my GP and went back to using Tressiba / Degludec as my basal and Humalog as my quick acting insulin.
Over the next few weeks, I was comparing my graphs and I noticed that I had less peaks and troughs and that my overall pattern was more stable.

Just recently I started getting really bad neuropathy pains in my legs and feet. They feel like they are burning constantly. I went to my dr who started me on Amitriptyline but I am not sure this is helping.
I have done so much research because I feel my overall control has improved. The neuropathy might be the nerves 'waking up' again or I read that even with a good HBA1c, that it could be caused from my post prandial BG going above 7.7mmol. If the latter is the reason, then I have no idea how to stay below 7.7 after eating a meal.

Today I am going to try get some Bentofotaime, Alpha Lipoic Acid and Evening Primrose oil. I heard these have helped many people.

Has anyone who has been through this got any advice? How long does this pain last because I cannot bear it anymore. Is there anything anyone takes for immediate relief? Sometimes I feel I cannot even wear shoes because my feet are on fire. Today i woke up and Im feeling the burn in my arms
I have tried Nurofen, Ibuprofen and no change. Last night I took 500mg paracetemol which helped a little.

I had an appoinment with a chiropodist and he said everything was ok and that I had a very healthy blood flow in my feet.

Id like to hear from anyone who has been through this and to know what you did to overcome this and importantly how long it took for the pain and burning to go.

Thank you Catherinecherub. OMG that has freaked me out..... Im petrified of having the test just incase they want a nerve biopsy and a lumbar puncture.
Im going to dose up on Vitamin B12 first.

Thank you to everyone who replies.
I will look into gluten free too.
I have just come back from Holland and Barrett. I bought B12, Niacin, Alpha Lipoic, acetyl l-carnitine, evening primrose oil and Omega 3 pure fish oil.
I am scanning my BG every 30 minutes so that I can stay below 8. Im also taking my insulin 15 mins before a meal to avoid a post prandial spike. Ill see how that goes for a few days.
Looks like Im going to have to lay off Christmas eating and drinking because I just cannot bear this anymore.

Ive been looking at low carb diets too and Im going to try snacking on almonds

Tonight, i might take 2 10mg amitriptyline tablets and see if that helps. So far today I have been managing to stay between 5 and 7. I wish the doctors knew how hard it is to stay within 5-7!!!
A morning coffee can send me up into the 10s!

Ive been on the Libre now for almost 3 months and my HBA1C has dropped by 1%. This must be attributed to my nerves waking up because my control now is the best it has ever been since 2001!

Is anyone taking Lyreca for neuropathy? Im told it is fairly expensive which is why its not easily prescribed. I been told that it works well for neuropathy pain.

Niacin, also called vitamin B-3, is a vitamin your body needs for a variety of functions, especially the metabolism of energy from food. Niacin also helps your digestive tract, nerves and skin work correctly. Niacin is water-soluble, so your body cannot store it and you need to make sure you get enough every day. According to the Linus Pauling Institute, a niacin deficiency is called pellagra, and it can result in nerve damage that causes neurological symptoms.

Acetyl-L-carnitine (ALC), a naturally occurring amino acid, may be an ideal therapeutic agent to address this otherwise recalcitrant condition. ALC is potentially effective at preventing peripheral neuropathy as well as lessening neuropathic symptoms once they have developed. Both animal and human data consistently demonstrate the neuroprotective and antinociceptive effects of ALC. In addition, ALC is well tolerated without significant risk of side effects or drug-nutrient interactions.

Extracted from the evening primrose plant, this oil is rich in omega-6 fatty acids, which are important structural components of cell walls. Theoretically, supplementing the diet with evening primrose oil, which is available in pills, may boost the repair or regrowth of damaged nerves cells.
In two clinical trials, taking evening primrose oil orally improved nerve function somewhat in people with diabetic neuropathy. .

In several studies, alpha-lipoic acid appears to help lower blood sugar levels. Its ability to kill free radicals may help people with diabetic peripheral neuropathy, who have pain, burning, itching, tingling, and numbness in arms and legs from nerve damage.
Alpha-lipoic acid has been used for years to treat peripheral neuropathy in Germany.

My dr has prescribed Gabapentin / Neurontin
I read the leaflet and did some research on the internet and now im too scared to take them
