I have had shoulder issues for over 4 years.In my shoulder joint I have had: Tightness, pain, loud clicking,and grinding. On my shoulder blade I have: severe burning , tingling, numbness, Loud grinding and a knot about the size of a nickel(almost under blade) I'm currently in the military and had no relief. I have had diagnosis after diagnosis! I have heard snapping scapula,impingement,spasms, and now bursitis. MRI has come back "negative", my x-rays as well. I have been to physical therapy for over 5 months and still no relief. What next? Please help!!!
