Where is my pain coming from now!!??? please help me!?

when i was 16 i was complaining about back pain and i kept thinking i was having a heart attack because every night for about 3 years i was having major heart burn feelings...after tons of tests they told me i have about 10 gall stones and was rushed to the emergency room where they removed my gall bladder because it was extremely close to bursting, and i guess it was probably one of the ugliest looking inflamed gall bladder they have ever seen. when i was 17 (only like 4 months later) i was at my beach house with a friend and my parents took the dog for a walk and i ended up calling them having hem rush back because i was throwing up holding my side unable to move. Once we decided to go to the hospital they told me my appendix was also very inflamed and needed to be removed. So now i have 7 holes on my belly! weirdly the 3 from my appendix are one on my belly on..one down below the belt..and the other on my left lower side which is strange because most people i know that have had the same procedure have it on the right side. Now only 5 months later my left side is once again killing me...feels like bad cramps..its the lower left side once again!!!...my dad is saying its probably just because my muscles are healing because it is right under the scar. I am not sure though because its been like 5 months i had the surgery in June. so if anyone has any idea what else is wrong please let me know...i feel like crap but our insurance is crazy high and my parents dont really understand when i say im in pain so if anyone has problems like that please let me know!!!
