Firstly, this is not a post for emergency help.
How can you tell if your reacting to ibuprofen? I know that might sound like a daft question but i'm not sure if it's just a coinsidence. Basically i've pulled a muscle in my upper back, which is making breathing a little tricky as it is, any how, i have taken 2 doses of 400mg ibuprofen, which normally i'm ok with but 2nite i have a tight chest and slightly breathless, been coughing all day anyway.
Would just be handy to know.
btw, i will seek help if it gets worse :o)
