A question regarding a health problem?!

I have a question, that only a medical person or someone this has happened to can answer!. I was recently in the hospital!. I was allergic to a medication, and went into respiratory failure!. I was told they worked on me for an hour!. I have been home a week, and am having a problem breathing!. With exertion I start to breath heavy, but at rest, I am ok!. I never had this before and am hoping this is only temperary!. If anyone knows the answer, please let me know!. This is really bothering me!. ThanksWww@Answer-Health@Com
