I have been getting cold feelings and pain in my elbow and down my forearm, now getting bad pins and needles in my hands at night. any ideas?

Radiculopathy: it sounds like this could be some kind of near nerve irritation. Most likely coming from your neck called the cervical radiculopathy. Treatment is usually consists of nonsteroidal anti-inflammatory and/ or oral steroids x-rays and MRI of the neck will also be needed. Also complete nerve or neurological testing of the upper extremity to see what your irritation is specifically affected
