<s>[INST] I had surgery last Wed. Surgeon put in a hemicap on my shoulder and took pin out of elbow. Had general anesth and a block on right arm. Since surgery my hand and fingers are numb. Working on that in PT. My hand and fingers are just always cold now. I wear a mitten when up and am putting a hot pad on it when in bed to warm it up. Just wanting to make sure that is ok. See my surgeon in the morning. Thanks [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Regarding your concern, I would explain that your symptoms could be related to a pinched nerve in the arm, probably due to a prolonged pressure in a certain position. For this reason, I recommend consulting with your physician for a physical exam. If your symptoms persist, performing nerve conduction studies may be needed. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Iliri </s>
