Hello doctor, I have had strong, persistent twitching in my left calf for over a week, sometimes with intermittent twitching in thigh, foot and buttock of the same leg. I am very concerned about this. I had a neurological exam (strength and reflex testing) at my GP, and he said all looked normal or good or no loss of strength or unusual reflexes. He ordered blood tests, and they have not come back yet, awaiting results. I have been exercising strenuously for the past few months and wonder if it could be exercise-related, but feel alarmed that it is on one side. Two weeks ago, I did not see a stair, stumbled and fell on my left hand, hurting my elbow, which has been in pain too. Physiotherapist hypothesizes this fall could have also brought on the twitch. I am seeking advice as I am quite scared that it could be a severe neurological conditon since I twitch about once every three seconds, sometimes even more, and it has only let up for a few hours before coming back in the same calf and part of the muscle. I have not noticed any real weakness aside from slightly wobbly feeling legs (but can still do a full workout on the gym, walk on heels and toes without difficulty, etc.). Mainly the anxiety is keeping me awake and probably making it all worse. My muscles feel tight and compressed at the moment, from calf up to left hip or buttock.
Hello. I passed carefully through your question and would explain that the twitching in this calf could be related to a twisted muscle or a pinched nerve (considering the straining physical activity that you have been doing lately and the falling). I would recommend performing nerve conduction studies and a lumbar spine X-ray study to exclude a possible pinched nerve or a bulging disc in the lumbar vertebral column. I would also recommend checking calcium, blood electrolytes, and vitamin D plasma levels for possible deficiency and inflammation tests like complete blood count, PCR (polymerase chain reaction), ESR (erythrocyte sedimentation rate). I hope you will find this answer helpful. I remain at your disposal for any further questions whenever you need.
