I'm sorry to hear that! Is this pain also similar to pain you felt after your first medial meniscectomy? It's normal to feel pain in the first few weeks after a surgery like this, and normally pain medications do the trick. But since you don't like pain meds and you're more worried about the cause of the pain, the best thing you can do is talk to your doctor on Friday. As long as you kept the swelling down through icing, your doctor may be able to recommend techniques for reducing pain or you may even be out of the worse part by then.
Sorry I couldn't be of more help! If you have any questions about my answer or if I didn't really answer you, please don't hesitate to respond
