I've been sufreing from lower back and tummy pian , consulted a doc he said that i've got a womb infection with out doin test what is rely wrong with me?

Can be many things: You really need to get a physical exam and possibly some testing, infection can be suspected but can't be diagnosed without testing.

Certainly could but.: Uterine or tubal infections can back and sacroiliac pain secondary to reactive arthritis. But the differential diagnosis can include colitis, crohn's, and many other diagnoses. I am also troubled by your not receiving emperic therapy. You may need to see another doctor particuarly an ob/gyn!
