Need help concerning costochondritis??
Can someone please...tell me what this is and how it feels? I have been having horrible pain in my left arm sometimes radiating down to my side and up to my shoulder. I also have a permanent sore spot on my lower left rib. A friend sugggested costochondritis could be the cause. I have had neck xrays, stress test, etc. with good results. I do have arthritis of the spine and other body parts, but have had that for a long time before this new pain started. Any help appreciated!
