Involuntary muscle spasms

Day 2 post op lapiplasty

Above the knee block has been wearing off for the last 5 hours. Spasms from my knee and downward. How can i get some relief from these? Oxycodone and ibuprofen as directed. Elevated 90% of the time. Anti-Inflammatory diet, lots of water and ice packs under the knee. What am I missing? 😫
