If you are still sore then i would push for a referral, or at least get a second opinion, just to make sure all is as it should be.
I had a 4th degree tear (& episiotomy, forceps, shoulder dystocia, pph) 11 months ago and i am still sore. You may need to be more specific about how you are sore, is it tightness, general discomfort etc? I was referred to gynae within weeks of the birth, have seen physio etc. I still have what i would describe as general discomfort but i put this down to the severity of the tear & the time it takes for scar tissue to de-sensitize.
