question: For the last 2 weeks I been feeling alot of back pain and on my left side and lower part of my stomach it hurt really bad for 2 days straight, but now not so much. I been feeling really tired and have headches once in awhile maybe multiple times a day. My back has been hurting alot to. Recently this past few days everytime I lay on my stomach it starts to hurt really bad in middlw section. Also I have been having mood swings. I was wondering what you guys might think I have. If you know any answer please help me out. Thank you so much.
