I m on my fourth day taking Methylprednisolone, 4 mg tablets, and I get this tightness on my chest, and kind of painful going towards my neck and back side, today the pain has transferred to the upper back between my shoulder blades, mostly on my right side, like underneath the shoulder blade. If I breath in deeply it hurts more. Should I call my doctor? Is this something that will go away once I finish it? Thanks
