I Had L4 And L5 Fusion With A Bone Graph

I had l4 and l5 fusion with a bone graph 4 months ago. had a fabulous recovery for the first 31/2 month ( no pain at all). about 2 weeks ago i started getting shooting vaginal,rectal and groin pain when squatting or slightly twisting. seems to be getting worse. I heard this is common right after surgery and should disappear in about 2-3 months but cant find any information of it starting this long after the procedure
