I have been having a constant twitch on my lower tricep for about 2 days now and this morning i woke up and it was still there. Its every second sometimes ever 2 or 3 and i am getting really worried. I dont think i have weakness and when i cannot see or feel it when i tense or even lift my arm but when i relax it it comes back. I slightly relieved as my friend told me he had an eye twitch for a week and he is fine but this is starting to stress me out and i am starting to focus on it a lot. If someone can give me advice or reassurance i would be very thankful. Thanks for reading
