How Can Recurrent Abdominal Pain, The Source Of Which Cannot Be Identified, Be Treated?

I have been in pain for about 6 months now. It started as a little pain in my lower stomach, over the course of about a week it slowly localized to my lower right abdomen. I was constantly peeing and there was no sense of relief after peeing like there normally is and I also wasn t letting out a lot of urine. Eventually the pain was constant but sometimes it wasn t as bad as others. The pain eventually got so bad I had to go to the hospital, the doctor finally got around to me after waiting for about 5 hours, she pushed on my side and just by the way I jumped when she pushed she told me it was most likely appendicitis. The nurse told me I would have to stay on an if overnight and get an ultra sound in the morning. The ultra sound didn t show anything but they said my appendix might just have been behind something so they decided to do a cat scan even though they normally don t do them on someone as young as me because they wanted to be sure. After the cat scan the doctor told me I most likely had mesenteric lymphadenitis and if he were to magnify my cat scan results he would see swollen lyphnodes and he basically said there was nothing that would get rid of it, but it would eventually go away on it s own. He said they would normally have someone with this stay on iv fluids for a few days but they just didn t have the room. The doctor suggested drinking Pepsi because it has a lot of sodium and that would help almost like how you gargle warm water with salt when the lyphnodes in your throat are swollen. So I took his advice and also booked an appointment with my doctor for about a month later. I told my doctor what the doctor at the hospital said it most likely was and he said that it could be that but brushed it off saying it was probably just menstrual pains, I m no doctor but I don t think menstrual pains are a permanent pain. He also said it could be a very small ovarian cyst which is too small to see on an ultra sound and therefore too small it worry about. Five months later I m still in the same amount of pain as when I went to the hospital.
