Fell 4 days ago and didn't feel much pain upon awakening the next morning was stiff and sore in my back along the rib area. Worked the next day and was in a lot of pain bending and reaching had a difficult time sleeping. Upon awakening the following morning day 3 was in such pain that getting out of bed was painful, walking up the stairs to the bathroom had me almost down on my knees because of the pain and spasms. Went to ER where I had x rays taken, when asked to raise my arms above my head again the pain radiated to the point I felt I was going to pass out, almost falling to my knees. Called ER today to find out about rib fracture(pain is radiating on my right side in the back of my ribs to the front of my ribs under bra line) the dr told me they found no breaks in my ribs but a spot on my lower lung on the right side. Was given tylenol with codeine for pain relief but it hasn't helped at all. Just wondering what exactly this is?
