Okay, I m 19 years of age atm, so this is going to sound like paranoia, but I d rather that paranoia be confirmed lol. I was at about 220 pounds, in a month I lost 25 pounds without any effort. I lost my sense of appetite( which has just recently returned) but during that time I had a dull ache in my upper abdominal. The ache today is more severe and my lower back is killing me, but I think it may be from poor form on bench pressing. Are these things to be worried about? They seem like pancreatic symptoms to me, but I know that s virtually impossible at this young of an age. Also the weight I lost was fat and has improved my athletic ability in certain tests, so it s not like I lost muscle mass or anything. what is your opinion? I d appreciate it if you shared it. Should I go see a doctor?
