Radation damage hip and leg pain plus perineum burning

Back in July and Aug I did the 33 IGRT adjavent treatments. Initial SEs were proctitis diarrhea and rectal bleeding. All but resolved. Now four months later I'm experiencing this pain in my left hip that comes and goes.I say comes and goes because when i sit for a short time and goto stand up I get this searing hot pain the shoots down my leg into my knee and lower leg some times its so bad I loose my balance,and almost fall to the floor. The other problem I'm experiencing is this nasty itching and burning on my Perineum Please forgive spelling. And my scrotum feels likes a peace of raw meat. Lotion helps to calm it down but it is relentless. Every week it seems to get a little worse ,including the hip pain . Currently I taking zoladex and psa is 0.01 has been there since May when I started. No difference since RT. So does anyone have any words of wisdom to convey. Or similar SEs .it's a five hundred km trip one way if I want to see oncologist and it's not an easy drive this time of year, so I booked an appointment with urologist in Jan that's only a hundred klics. Would like to have a good arsenal of questions to ask when see him. In turn he will forward concerns to onc.
Thanks for your time

Thanks forbthe reply Enghish alf, the pain in my hip starts basically from the exact spot where the tattooed me. It doesn't feel like a bone pain more, ike a bursa sac but readiatess across from my hip down the front of the leg in into my knee and calf.I started noticing it about a month and half after RT.Didn't pay much attention to it until lately is just been getting worst. As far as the scrotom irritation its been slowly getting worse. My oncologist. Told me not to use lotion during the treatment because it would interfere with rad beam. No sure what the hell iis going on maybe nerve neuropathy hard to say hoping to find some one with same type of SEs
