Interior arm pain, tightness, and loss of sensitivity

Patient: Hello. I am having extreme tightness on the inside of my arm. when i hold my arm out to the side, there is an extreme burning sensation, and i have to pull it back. also, the area feels like it has been anesthetized, i can not feel hot or cold on it. i held an ice cube on it until it melted and did not feel a thing. i noticed it when i woke up about a week ago, and was just wondering if i should actually see anyone about it. thank you.
