Post-op pains (appendectomy & hematoma)?

I had 2 surgeries almost 2 weeks ago. My appendix ruptured and 3 days after that, i had to go another surgery due to hematoma. Right now my wound is closed, but after a day of school, I had this pain near my pubis bone (left side only). The pain is manageable but it won't go away even i take up analgesics. Any ideas please??
