I've been sleeping with my feet propped up on pillows to prevent varicose veins. I'm also doing yoga and bike riding for some exercise, and I take fish oil and sometimes flax seed oil.

Sometimes I wake up in the middle of the night and I can't move my right foot. When I try to move it, it hurts, and I actually yell out in pain. After a few seconds i'm able to move it without pain again.

I'm thinking it may have something to do with circulation. I don't know if it will only happen when my feet are propped up. If it's happening because my feet are propped up, why is it always and only my right foot?

Does anyone have any ideas? I think it's completely bizarre.
