Sharp pain in right side crease area where thigh meets groin. Loss of full range of motion-can't move leg up to put socks on. Pain for months now.

Groin pain. The commonest cause of lingering groin discomfort is strain or injury of the inguinal ligament which takes many months to heal. Do you recall any strain of the groin area in the past? Occasionally pain in the groin is referred from a hip joint problem. I recommend an examination by a general surgeon to check for hernia or evidence of ligament or hip pathology.
