The ibuprofen is not working. :(

My breathing problems have ceased, however I still feel the same sharp pains in my left upper rib area. They started over Christmas break, and I first noticed the jabs when I would wake up in the middle of the night, lying on my stomach. I normally sleep on my back, so I would painfully flip over and go back to sleep. That still happens almost every night, and now sometimes on my side. Today, I had pain just about all day, and it wasn't until I'd turn or straighten up or hunch down that I would be victim of these pain attacks. It's really starting to annoy me. But why should I go back to the doctor? It's not like I feel or see anything. She's run the tests she had. She may just send me to the hospital for Xrays or other super-expensive tests. Sigh.
