Talk about some kick ass pain. The same thing happened to me about 6yrs ago. I wasn't feeling well, (no pain at this time) so I gave my docs a call. It had been going on for a few days at that point, so I figured I better get on top of it before it landed me in the hospital. I called them, and they gave me the option of coming to the clinic and getting evaluated for a possible hopitalization, or try oral antibodics and give them a call back in a few days. Of course I took the oral route. They prescribed Cipro and Tobi. I went and picked it up and took it as soon as I got home. A few hours later, it started hurting for me to breathe, and it just got worst. I tried to blow it off, I figured it was just gas, since i'm not one to complain much, but it only got worst. We'll to make a long story short, I went to the ER and they said I had (not sure on the spelling. had to change the "C" at the beginning to a "K" because the website edited it as a bad word) Kocksackies Virus AKA "the devils grip". They said that it results from irritation of the lining of the lungs, usually due to a bad lung infection, so I ended up the the hospital anyway. The pain eventually went away, but nothing they gave me eased the pain. The only thing that helped was sleep because I wasn't awake to feel it, which because of the pain, couldn't get much of. As you know, exercise is the key, so the more I exercised, the better it got. I was still sore from the pain for a few weeks, the big dog pain was gone. Tori 21 w/cf
