Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can.
Well, this physical activity may have predispose to your symptoms.
Hand numbness is usually caused by damage, irritation or compression of one of the nerves or a branch of one of the nerves in your arm and wrist.Diseases affecting the peripheral nerves, such as
diabetes, also can cause numbness, although with diabetes similar symptoms usually occur first in your feet.
However, your symptoms indicate that there is compressive neuropathy which is seen in carpal canal syndrome or cubital syndrome. You need to do EMG first to confirm diagnosis and then it can be treated with local
steroid shots or surgical decompression. Also,
physical therapy may be beneficial.
I hope I have answered you query. If you have any further questions you can contact us in every time.
Kindly regards. Wish you a good health.
