Am really struggling as I always use to sleep in foetal position or on side stretched out but I get pain down my right leg particularly in thigh and around my knee. The pain will literally wake me up, its a deep ache, sometimes like a buzzing in my thigh. I try to go to sleep on my back but turn in my sleep. Does anyone else get this? I've tried pillow between knees. Weirdly regardless of whether I lie on my left or right side I get the right legged pain.
