I've been having this tingling sensation in my hand. when i hold stuff my hand goes numb. could it be carpool tunnel ?

Carpal Tunnel: Carpal tunnel presents on the thumb side of the hand, especially involving the thumb, index and middle finger with numbness and/or tingling, along with discomfort and sometimes weakness. It can radiate up towards the neck. Not sure about your case, but a simple exam should tell the story. Good luck.

Hand Consult: Generally tingling in the hand is an indication of nerve compression. Find a hand surgeon in your area and schedule a consultation.
