What causes pain in upper left back?
Patient: I ve been told I have Epstein barr virus (again, had it 20 yrs ago too) and that my numbers are off the charts (to quote dr!). My concern is I am having a sharp dull pain in my upper left back that will not go away. Have had back issues so can t tell if my spleen or not? Is it safe to just wait? Dr ordered a spleen ultrasound, but don t even have the prescription to book apt yet. Also having very generalized pain to touch everywhere around the area. Doctor: You could be having a muscle knot. You can get a steroid shot in that knot for relief. Consult your Pain Medicine Specialist.
