Proximal neuropathy revisited

Some months ago I posted on the above topic, since then I have seen my GP, whom I normally have good faith in - she is very approachable and reasonable to my suggestions and concerns, however, she immediately told me that proximal neuropathy of the hip (commonly called sciatica) always affects both sides, mine is one sided to date, but much of what I have read suggests otherwise. I did not like to challenge her on this, she did a few tests my asking me to move in certain ways and she found a point in my lower back which seemed to pin point area of source of pain. Then she gave me an exercise sheet, which quite frankly I found to be quite futile. Recently the pain has come back and I also have noticed that when crouching down (ie to reach in fridge) I need to hold on to something to lever myself up again, not because of pain, but my legs just do not seem to have the strength to lift myself. Feet often feel very cold, and burning - sometimes fronts of them and shins feel like (as someone else posted) hot water is being poured down them. I saw the Diabetic nurse for my yearly check, she found no problem with the pin prick test, I can feel in my feet but that does not detract from the sensations I have in them. Still feeling this is a diabetic problems, as it seems to fit, the pain is definitely a nerve pain, or akin to toothache in the leg as I describe it. Anyone have similar experiences? Also, there was a lady who said she found some pain relief from US if she reads this maybe can get in touch for more information please?
Wishing you all well - we are all in this together

Just wanted to add that my meeting with Diabetic nurse did not get off to a good start, this I covered in another post, however, it ended on a friendlier note (some people felt I should have reported her for the way she treated me), however, that aside, I have just thought about this, although she did the foot checks she did not trouble to ask me very much about any problems I might be experiencing. I did mention the leg pain, and that I had seen the GP, she told me that pilates would help - any thoughts on this idea please? Also, although I have had to get a further blood test as GP was a little concerned on kidney results - but otherwise results were acceptable.

Thanks all for your replies, wow, some of you are really suffering and mine seems like so little in comparison! However, it does hurt and cause discomfort and I will definitely follow up if there is no improvement.
