I am a 20 year old male, about 6'1, 175 lbs. For the past couple months I've been bothered by sharp pains, mostly in my lower left side in the area between my belly button and the inner corner of my hip bone. However, it also occurs sometimes on the opposite side in the same area. It seems to happen at random times and does not seem to worsen after I eat. I have been urinating without problem and staying regular as well. It gets a lot worse whenever I am laying down or have my stomach stretched out in some way. It's a quick, sharp pain that will usually cause me to tighten my abdominal muscles and curl over immediately when I feel it, making it extremely difficult to stand up straight. Some days it will not bother me at all but other days it will be off and on for most of the day. A couple weeks ago after a few days when that pain was getting exceptionally more frequent I went to the hospital but they could not find anything during initial testing. They suggested I come back for an endoscopy. The pain seemed to stop by the time I left the hospital the next day and they gave me 30 Protonix. The endoscopy a few days ago did not yield any real results, only finding minor irritation that they suggested could be the beginning of Acid Reflux, but I'm not sure because I do not have many of the symptoms (no nausea, difficulty swallowing, or chest burning sensation) and they could not tell me that Acid Reflux was definitely the cause. I do not smoke cigarettes. I drink only a couple times a week and rarely in excess. They thought maybe the fact that I was chewing tobacco (which I do about once or twice a day) was causing the pain to flare up. One day I actually tried not taking the Protonix and chewing tobacco to see if it would get worse, but I didn't feel the pain at all. The Protonix seemed like they were helping for a short time, but I'm really not sure. I forgot to take my pills yesterday and I started having pains around 3 o'clock, so I took a pill. I continued having worsening pains throughout the night and was awakened this morning by some of the worst pains I have had so far. I took a Protonix around 7:30 am (it is about 7:30 pm) and the pains are still pretty bad when I'm not crouched over a keyboard. I don't think it is helping. Any guesses or suggestions as to what this might be? Or what should I do now?
