What nerve causes tingling in the right forearm and hand?

Tingling in the right forearm and hand is often caused by irritation or compression of the median nerve, which runs down the arm and into the hand. This condition can be linked to carpal tunnel syndrome, where the median nerve is compressed at the wrist. Other potential causes include ulnar nerve compression or cervical radiculopathy, where nerve roots in the neck are affected. It's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
