I took Advil for about a week because of muscle aches and headaches. But I have highly suggested kidney disease so I shouldnt take anything with asprin.

I've been ignoring it for awhile but I've had a stomach ache and nausea and right now my stomach really hurts. I also have heart burn. I just took a pepcid and I used the bathroom a lot half an hour ago and it seems to be getting worse. Its like in the middle of my stomach. The last I checked I didn't have a fever.

Should I be concerned? I think I last took the advil yesterday morning.
