I started to have lower and upper left abdomen pain yesterday. the pain is constant and gets worse when lightly touched or when i move. causes?

Can't tell here: Could be lots of things, ranging from musculoskeletal problems, constipation, to serious internal issues, including but not limited to: ulcer (with or without complication), gyn issues, kidney stone or infection, bowel issues, infections, etc. See your doc.

Need exam: Depending upon where you are in your cycle and if it came on all of a sudden, you may have a cyst on your ovary or a ruptured cyst. There are also some more unusual things. An exam would be helpful.
