Small but definite -: Chance with your hx of prostate cancer. See your orthopod to get investigated. I am sure your oncologist must be following you if its only been 2 yrs since you had radiation. I am sure he (she) can also tell you. Prostate cancers are generally amenable to radiation treatments and pts do very well. So check with your rad, oncologist ; an orthopod, as early DX means early treatment. Good luck.
