I Have Had Occasional Difficulty With Weight Bearing On My

I have had occasional difficulty with weight bearing on my right leg at least once a week for approx. 2 months. Until today, it had only occurred when I first woke up and if I stretched my legs. I would get a sharp pain in the front of my right thigh followed with the inability to bear weight on my right leg only. It lasts less than 30 minutes and resolves with rest. Today it happened midday after sitting for approx. 15 minutes. I stood up, felt a sharp pain in the front of my right hip, and was unable to bear weight. It was gone after sitting for 5 minutes.
