I have symptoms of right side face numbness and right thigh lateral numbness, swelling and redness. also, when standing for an extended period or walking, blood pressure goes up.

See your doctor: This could be one of several problems, including trigeminal neuropathy, meralgia paresthetica, or of inflammatory origin. It could even be from brain origin. The swelling and redness are the most important parts to get sorted out, as the cause may be associated with numbness. BP is likely to be secondary. Don't try to sort this out without medical help. It sounds serious.
