Please, please help! My son has had arm pain, below the shoulder, above the elbow for five months now. He has had 4 xrays, an MRI, and a bone scan, and they can not give me a diagnosis. Been to PT numerous times. They said he had little league shoulder, a broken shoulder, a large calcium deposit, nerve damage, he had a cortisone shot in his joint, (with no change), every time I take him they can not give me a diagnosis, then change what they think it is. I took him to the chiro, he has had cupping done. Please help on anything anyone can think this is and I will try it! Please help!
