When I was a teenager I was always considered "underweight." (5'7" 120-125 pounds) Around the time I was 17, I had this sharp pain in my side and was told to go to the hospital. I didn't go and the only thing that helped was putting snow on the area to numb the pain. It lasted a couple hours until I finally passed out. Since then I've been gaining weight with no way to lose or control it. I've gained over 150 pounds since then, almost 9 years ago. My feet swell now and I have facial hair. Any ideas on what could have caused it?
