I have a burning sensation in my right fore arm. it is worst when i use the arm for lifting, hammering, etc. what do you think it could be? thanks

Burning arm pain: Burning arm pain especially during physical strain can be due to some nerve irritation in the cervical spine... It can be from a disc bulge or arthritis with maybe a bone spur, where strain compresses the neck alittle more due to muscle compression. A form of cubital tunnel syndrome or carpal tunnel syndrome needs to be excluded (elbow or wrist compression). Fatique is also possible maybe...
