gazelle, most of the time, it is hard to reply to a person's questiion without all the info. It is good to have the ability to scroll down and see if the person, for instance, has had the same problem before. If you have a question that is very important to you, you can change the name of your thread---just tag one or two moderators and ask them to do that. To tag someone just type an @before the name they use on bonesmart. For me, it would be @skigirl---the tag turns blue after you post it. Most of the time, a prompt comes up while you are typing with the official name of the person. I have trouble with MaryO sometimes---so, if I type MaryO---her official name which is MaryO51 pops up for me. Let me know if you don't understand any of this!
I took exactly what you are taking---one or two 5 mg Oxycontin every 4 hours when I first came home from the hospital. But, it sounds like that might not be quite enough for you since you are having pain. I would call the OS office and ask for the 7.5 which is the next up strength---tell them you are having pain despite the drugs.
Most OS offices are rather stingy with pain meds. I would get enough for 10 days. I finally protested because with my insurance it was the same price for 10 or for 50. Finally, they gave me 25 at a time. If your OS office is far away from you, have them mail the script---you have to get a physical script for narcotics which are Class II. So, call now before you are completely out of them---ask for the nurse, it is faster or the PA if your doc has one. It was so much easier for me to deal with the PA---he would give me 50 at a time!!
The first two weeks are a critical time for pain---I mostly lay with my knees elevated on three pillows with ice packs and took one 5 mg Oxycodene every two hours for the first few days. ( one every two hours is the same as two every four hours) Then one every four hours, then one every six hours.
Also, in the beginning, pt is mostly massage and gentle stretching of your knee---I had no pain at all in pt and never took pain meds just for pt. Do NOT let the pt hurt you or your knee--it is not necessary at all. In fact, it is counterproductive if their actions cause additional swelling. For now, your goal should be to get the swelling down as much as possible. Anything that interfers with your goal is not to your benefit.
Don't worry too much---but call right away about the pain medications. If your OS is uncooperative, your GP might help.
