I did have tingling,twitches,jerking. And now swollen ankles and feet and a feeling of I am wearing something on my lower legs and lower arms. Feels like it's all up my left side now, if I run the top of my left foot . You can feel the tingling . I was on effexor for the problems and my so called aniexty that I didn't have , I have seen an internist, nueroligist and a couple useless drs. I've had 2 Mri , and nothing. And a nerve conduction test. ThY refuse to do N emg or other test because they say it's no nueropathy. He said my Brain was irritates, I wonder if it's sfn.

I also have developed muscle twitching in the last month or so in my legs. The neuropathy seems like it is getting a lot worse. It used to be just my feet, now I have stabbing in my ankles and the pain is halfway up my calves. My muscles have started twitching and my calves feel like they are cramping. I take magnesium citrate. The pain has gotten so bad that I can't sleep at night. Also started new weird sensations like water dripping up my legs.

My neuropathy started with twitching which my neurologists insist are benign fasciculations. Truthfully I don't care what they call it as long as it stops because they made it impossible to sleep. I had the burning and all the other sensations you are describing but at the beginning they were not as much an issue as they later became. I am on Gabapentin but I am looking to get off it. Some people are helped by it. I am looking for a doctor to prescribe a topical with Gabapentin and other ingredients that I can use as needed instead.

Some things to try:
Slow Mag (1 in the morning and 1 at night with a meal)
Morton's Epsom Lotion
Aspercreme with Lidocaine (some people prefer Menthol instead)

Check some of the threads on topical creams and supplements. There is a wealth of information. I hope this helps.
