Hello,
It looks like you are suffering from
Focal Dystonia, it can arise due to no cause at all but it can be hereditary or sometimes due to some disorder in the
Basal ganglia. The factors that may trigger it are fatigue, stress, caffeine,
drug abuse, etc.
Focal dystonia is basically a Neurological disorder. You are suggested to visit a
Neurologist, get examined, evaluated. Get done all tests (CBC, Nerve conduction tests,
Urinalysis, Imaging (CT, MRI, EEG) tests) & get treated at the earliest.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
