Will compression stockings prevent signs and symptoms of a blood clot in the leg?

NO. While compressions stockings help in the prevention of vein blood clots, their use typically does not hide or mask the signs and symptoms of a leg blood clots. But unfortunately many people with blood clots do not have any symptoms in their legs to let them know that the clot is there.
