I keep feeling this like tapping inside the back of my leg. It s hard to describe, but I will do my best. Feels like a trembling or maybe a pulsating. It s very faint but enough to be noticeable. It comes and goes, but when it s there it taps every few seconds. Then it will be gone for a while. I m not a smoker, but I am morbidly obese. I m not on bed rest or anything like that, but I have been sitting more than typically over the past four or five days. I ve never had an injury on that leg. I m worried it might be something serious like a blood clot or something along those lines. It seems like it comes back when I m bending my leg (when sitting), but if I lie down it seems to stay there. Walking/standing seems to make it go away. I m a male, 34 years old. I took an aspiring for an unrelated headache. It seem to go away for a while but it s back. Not sure if that caused it to go away or if it was something else.
Hi there. It could be a muscle spasm which could indicate electrolyte disturbances or pinched nerve in the lower back. I advise you to avoid bending forwards or lifting heavy weights. Eat plenty of fresh fruits and green leafy vegetables.  Chat Doctor.  Avoid junk and fatty food. Exercise regularly to keep fit. You can apply hot water bottle to the area if it is painful.
