What would cause my right foot to "slap" the ground when i walk? is it possible there is something wrong with my right leg? i can't control it.

Foot drop: This sounds like foot drop. If recent, it may be temporary due to a nerve injury. However, if this is ongoing, you should have it evaluated to determine if there is a more serious nerve or muscle injury.

NEED EVALUATION: Need to see your pcp could be some neuropthy/ but first of all needs a good physical exam and medical history( diabetes/history of stroke ).
