<s>[INST] I started to get an intermittent pain radiating from the top of my right thigh down to my knee. Almost like an interior cramp. It happens about every 30 seconds to a minute and last about 2-3 seconds each time. When it hits it really hurts, then goes away quickly. [/INST] Hello, I have studied your case. Possibility could be of lumbar disc compressing nerve root leading to sharp pain in thigh to knee. I will advise you to do MRI spine to see for any disc bulge. Another possibility of arthritis X-ray will rule out arthritis. For these symptoms analgesic and neurotrophic medication like pregabalin can be started consulting your doctor. Physiotherapy like ultrasound and inferential therapy will give quick relief. I will advise checking your it B12 and it D3 level. Hope this answers your query.
