Pubic pain? Diastasis Symphysis Pubis (DSP)?

I am new here. I am having pain in my pubis area now for about6 mos. I am not of child bearing age and my baby is 16. Could I have PBS this long after child brith or can women of experience this with out associations with pregnancy/childbirth. I been to the dr. i have recieve no diagnosis as of yet. I've searched the internet and some of these symptoms descirbes my pain.

Over the past couple of years I have talked to my doc about it a few times, but they just give me a blank stare, and don't care. This summer I shattered my left Tib/Fib, and also reinjured my pelvic ligaments. Now that I am finally walking again, or limping I should say it is really painful. My physical therapist is a woman who understands pain and is going to try to work with my on it, I have no idea what that means but if it is helpful I will be glad to share the info with you. When its real bad, a three day regiment of anti inflamatory meds helps,, ibuprophen (800mg) every 4 to 6 hours. Its a lot, but its the only relief I have found at all.
Hope your feeling better soon.
