Hi Violetmom, hope you've had a good day and sorry to hear the thigh twitch has brought you back to a dark place. These symptoms are such a roller coaster ride that with new changes bring back old fears. My suggestion is keep yourself busy, try not to focus on it, exercise (show yourself how strong you are) and if you feel the anxiety has taken over a trip to the doctor is a good idea. I felt the same way when my thigh was thumping constantly but it did go away. I've had other constant twitches too..my hamstrings, eyebrows and almost everyday the arches of my feet. When I told my neuro about all the types and location of twitches I experience he wasn't concerned about any of that, didn't even care about frequency, how long they lasted. He focused on strength of those muscles. (really good neuro prior director of the ALS clinic) Veryworried, how video to me looks like a jumpy twitch I get over my whole eyebrow. Very weird looking but like your neuro said harmless.
