Using too much ibuprofen put me in the hospital for 5 days. I had a nagging shoulder problem due to lifting and bjj. Instead of letting it heal properly I decided to just use ibuprofen and push through. Well it caused irritation in my intestines....which then caused my intestines to swell shut. My stomach swelled up because nothing was going through my body. Horrific pain. I ended up with tubes up my nose down to my stomach to relieve the gasses and pressure. No food or fluid for 4 days. Just the iv. So be really cautious about using ibuprofen.
