Detailed Answer:
Hi, Welcome to Health care magic forum.
As you describe it doesn't appear to be due to the nerves. It appears to be due to an allergic reaction, to some thing for which you may be allergic.
You can find the thing for which you are allergic ,by noting down every thing you have used on the day of the sensation, and try to find out the thing, you have used on that day, and omit it, and continue like that.
You have tested for diabetes, deficiencies, E.M.G,for neuropathy's done but all are negative. So neurological effect is excluded.
You also have
sharp pain at the fore arm, or any place. You got tested for lymes, MRI of lower spine, for problem at L1and 2 since several years.
Now you are having pain in the left hip also.
The pains could be due to the
osteoarthritis, which is tend to be present at this age.
lumbar spondylosis,
disc prolapse etc.You are using now sotalol,
tamsulosin, and B12 100mg.
I usually prescribe to my patient with such symptoms Injections of
vitamin B1,6, and 12 for 10 consecutive days, and then periodically, along with their usual drugs.
If you have any doubts, regarding this matter i am happy to clear the doubts.
Wishing for a quick and complete recovery. Thank you.
