Medication help for heel cord surgery?

i got that done when i was about 5....i had CP (Cerebral palsy) and my leg muscles were really tight so did a heel cord surgery and hamstring release. i dont really remember it muchh. but im pretty sure they gave me really strong medicine for it. sorry. not much help. but decided to share my story which is similar to yours. one suggestion: keep everything really stretched out....even if it doesnt feel tight.you have to stretch in some way every day. atleast stretch and try to reach your toes.
