[|Human|] Hi, whenever I sit on HARD chair for more than 10 minutes, my left calf becomes numb and tight. When this happens, I will walk around and it becomes better. If I have sat down on hard chair for too long and the numbness is bad, I will have to lie flat on my back on a SOFT bed for hours, then the numbness goes away. But this numbness and tightness on calf doesn t happen if I sit on soft sofa or lie on soft bed even for hours. Other parts of the leg and my back are ok. No pain. May I know what s wrong?
[|AI|]  Hi, thank-you for providing the brief history of you. As per your history I feel this is related to nerve pathology due to compression of the nerve in the sciatic notch area due to which there are changes in the sensory system and the numbness is feeling. Also, you should get your vascular system checked once as due to venous insufficiency there might be such symptoms as well. So a thorough clinical examination is advised. Regards Jay In Chat Doctor.
