Hello,
You have history of cyst removal from your wrist (R), 8years ago. Presently you can bowl and do other things with your affected hand but writing is becoming a challenge. Your right hand starts shaking so much that you lose control. The possible causes for your symptoms are use of
nerve block during cyst removal, sometimes nerve block may damage specific nerve or cluster of nerves. It may also occur due to damage of the nerves that run through the surgical site.
Nerve injury (nerve cut) may also cause the manifested symptoms.
Surgical
nerve damage may cause permanent nerve damage can be a potential side effect of surgery. Risks should be informed before hand to the patient. Other factor that may cause similar symptoms are
essential tremor, Parkinson's disease, multiple
sclerosis, etc. You are suggested to get clinically examined by a
Neurologist, get all nerve conduction velocity test and required investigations done. Get treated at the earliest.
Neglect may make symptoms worse and affect eating, drinking, writing, and all the other daily tasks you do with your hands can become a bigger challenge. In the meantime, stay active. Get connected to a physical therapist and do regular exercises, take food rich in
vitamin B12. You can also take supplements. Stay away from stress(physical and emotional), avoid taking alcohol and caffeine as they may make symptoms worse. Control your blood sugar level at all cost and get treated if you have an overactive thyroid.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
