Forearm pain w/ swelling bruising & tender spots near the ulna, makes popping sound when arm is moved sometimes & lightheaded sometimes, can move it?

Doctor can evaluate: There are enough arm symptoms present, so one should see a primary care doctor or an orthopedic doctor to examine the arm. Most orthopedic doctors can do x-rays in their offices, so that might make it a one-stop trip. For the lightheadedness, a primary care doctor can evaluate as to why, such as anemia, low blood pressure, infection, hormonal problems, etc...
