Have Severe Pain In The Hip When Walking Also

I am experiencing hip pain. It began as a sharp spasm like pain when I was laying down to sleep and moving the right leg to position it for sleep about 3 days ago. I have had this condition since. I have used cold pack and a heating pad that give temporary relief, Ifropropin gives temporary relief. Now, I have pain when I walk. I can sit and stand but when I lay down and extend the leg a sharp pain occurs. I am 66 and am active. I returned from a weekend of down hill skiing with no symptioms and began having the pain a day later.
