Patient's Query

Hello doctor,

My bicep muscle has been twitching and my leg and arms muscles twitch occasionally. I am super anxious about amyotrophic lateral sclerosis (ALS). I am 36 and postpartum six weeks but I cannot stop obsessing about ALS. Please help.

Welcome to icliniq.com. I understand your concern and would explain that there are a lot of other benign causes that may lead to fasciculations like anxiety and insomnia, benign fasciculation syndrome, vitamin D and vitamin B12 deficiency, an electrolyte imbalance or thyroid gland dysfunction. For this reason, I would recommend performing some tests: Complete blood count, blood electrolytes, thyroid hormone levels, vitamin D and vitamin B12 plasma levels. Nerve conduction studies would help to definitely exclude amyotrophic lateral sclerosis (ALS) and put your mind to peace. You should discuss with your doctor on the above tests.

Same symptoms don't mean you have the same problem. Consult a doctor now!
