Hi, thanks for writing to HCM.
From the description, I feel that you are experiencing " Muscle fasciculations" or simply called
muscle twitches in the arm. These are involuntary (occur without your effort) movements of a part of the muscle usually occuring as the body's response to fatigue or overuse.
Causes of muscle twitching are numerous and a few of them are -
* Anxiety - is the leading cause of
involuntary movements in muscles
* Vigorous body workouts in the form of exercises
* Too much consumption of caffeine and alchohol
*
Nutritional deficiency especially Calcium,
Magnesium, Vit B6 & B12
* Side effects of certain drugs like Ciprofloxacin
* Neurological diseases like multiple sclerosis, peripheral neuropathies etc
Follow the below guidelines
*Gently massage the affected muscle
*Hot fomentation (dont use ice as it may worsen the condition)
*avoid
dehydration and drink plenty of fluids after workouts
* take a healthy diet rich in vegetable and fruits.
Hope this information is helpful. Good day
