This is exactly what happened to me. I'm now at about 90% from a groin pull that occurred in mid-January. I reinjured it every time that I thought it was sufficiently healed to squat again.
I finally went to an A.R.T. guy who works with athletes. It's taken several (painful) visits to break up the scar tissue that had formed and to regain flexibility, but I'm squatting again and feel better than I have since my injury.
My advice is to get medical help. Otherwise you could end up in the same injury cycle that I did and take much longer to recover than need be.
