Oooh I hate to even say this but it does sound like your hips. They told me when the pain hit my groin area it was time for surgery. I haven't had the surgery but it gets worse and I can hardly walk or even get comfortable in bed now.
I sorta bunch up a huge comforter and push my legs onto it to try and get comfty at night. I am in my second year of pain but this year is the worst.
Funny thing, sometimes it rains (i live in Fl) and the pain isn't so bad and then a nice sunny day and I am like hurting big time. I get pain in my thighs and down the front bone of my leg also. The Doc said it was the arthritis.
Get an x-ray it will tell you. I wish you well and hope it isn't but.....
