I recently had cervical spine issue…possibly related???to…This: I lost ability to take head to knee in parvrtta upavishta konasana instead I get pain in back upper thigh…im stumpted. If pulled hamstring then wouldn’t it hurt in other forward bends also?..Why only this pose…it radiates from hip( kinda like somethings a miss) and feel a bit of something in shin to big toe(not much, tiny undercurrent but…)
I’m investigating the pose and what is happening anatomically in parvrtta upavishta konasana so I can heal this and would like any input.Thanks my.fist time posting and way too late so good night.
I want to clarify that this is the pose you are referencing. Is that correct?
My guess (from afar and without seeing you and knowing incredibly specific detail) is that you’re impinging on the sciatic nerve. That means that either you are compressing in the lumbo-sacral region or that your piriformis is in spasm and pressing the nerve there on its way down the lower limb.
