What causes a twinge in the leg while lying down?
Patient: I am 56 woman and have been working out and doing yoga for about a year and have loset 70 lbs. 2 nights ago I started to get this twinge in the right side in one spot. It only happens when I lye down. I have sciatica but I didnt think that this could be the problem. Whatever it is is seems to be near the surface muscle. Doctor: Hello,  Your symptoms are suggestive of benign fasciculations (BFS). There is no need to worry, as it is not a serious condition. It would stop on its own. It commonly occurs due to muscle exertion.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Sudhir Kumar, Neurologist
