I'm a 15 year old female and have had continuous undiagnosed abdominal pain for about 3 years now. When it was first investigated it was found that I have an ectopic spleen (my spleen is next to my left kidney) so I underwent surgery to 'fix my spleen in place' where the surgeon found that I had abdominal adhesions and also my left ovary and fallopian tube are pulled out of the pelvis. 

In the operation I had the adhesions removed but my spleen was left in place. About a month ago I started to get more pain in the middle of my abdomen and slightly to the left, sometimes I also get pain in my left shoulder which is unusual for me. Has anyone got any suggestions on what it could be and ways I could help please? I've also been fainting when the pain gets worse too if that helps.

Many thanks
