The conversation between human and AI assistant.
[|Human|] Hi. I have a pain that I think starts in my knee and goes up my thigh. It is a dull, gradual ache that I cannot pinpoint. I was taking statins a few months ago and stopped because I thought it was affecting my muscles. I notice it most sitting, driving or going to sleep. There is no comfortable position. I felt the statins affected my thigh muscles, but this feels a little different, almost like bone aches.
[|AI|]  Hello! Welcome on Chat Doctor ! Your symptoms could be related to a pinched nerve or a bulging disk in the lumbar region (compressing the sciatic nerve). Coming to this point, I would recommend consulting with a neurologist for a physical exam and some tests: -a nerve conduction study to exclude a pinched nerve or neuropathy- a lumbar spine X-ray study (a lumbar spine CT scan may be needed). Some blood lab tests (complete blood count, PCR, Sedimentation rate, blood electrolytes, vitamin D levels) are necessary too. You should discuss with your doctor on the above tests. Hope you will find this answer helpful! Best wishes,
