What Causes Pain In Hip And Leg?

hi i m a 58 yr old male with pain that started in right hip then went to the left hip, then down the leg. which has been this way at least 7 days. on left side of calf at about 11 o clock on the leg it is numb, white, feeling like a charlie horse that does not get any better or lessen. it is excruciating pain. not able to stand for long or walk long due to the pain in the leg. squatting or sitting seemed to relieve the pain but as soon as standing and moving about the pain is back again. have been given tylenol 2 with codine. morphine shots twice in same day. nothing is working to eliminate the pain. please help
