Has anyone experienced something like this: lying on one side it starts to numb-tingling, flipping over to the other side doing the same after a few minutes. Sometimes I sit as if periodically everything from head to toe is slightly numb or tingles. The pressure is always measured in normal range, there has been no increase or decrease ever. If I walk then after some time I feel that my feet start to hurt, although I've improved not much, so there's no extra weight. Has anyone experienced this?
