Achy Thigh Muscle Right Leg. Seem To Have Jammed It,

Achy thigh muscle right leg. Seem to have jammed it, now hurts to walk. Limping a little but noticeable. Hurts when I extend muscle or put weight on it while walking,,,,not when standing. Pain level while walking low to moderate. When walking feel it sometimes where leg connects torso.
Has lasted a few weeks. Does not wake me up at night...sleep well Do have trouble raising leg up from either standing or prone position.
