My right forearm feels very tight when i move my hand around and bend the wrist. is this a sign of a blood clot?

Merits evaluation.: Any trauma to the arm, whether mild or severe, can cause the muscles or blood vessels to display consequences: muscle strain or tear, bleeding and blood clots to name a few. A careful examination by a qualified doctor should result in the correct diagnosis and therapy.

I do not believe so: Blood clot could happen in the arm but they are rear, usually the arm will have swelling and pain more intense.
