You really are doing well, though it may not seem like it. You are making good decisions.
My surgeon was ok with me taking ibuprofen and Tylenol. I always had something to eat when I took any medication, even if it was just a cracker.
I took something every 3 hours and alternated ibuprofen and Tylenol.
For example, ibuprofen at 6 am, Tylenol at 9 am, ibuprofen at noon, Tylenol at 3pm, ibuprofen at 6 pm Tylenol at 9pm.
Because I wasn’t taking any other medication with Tylenol in it I took a fourth dose of Tylenol during the night, making sure it was at least 6 hours after the previous dose and therefore staying within safe limits for me.
Each dose of the same medication was 6 hours apart, but it gave me something every 3 hours.
It didn’t make me pain free but was enough to help.
I do enjoy biking the local trails, I want to get back to it sooner than later.
You will get back to riding your bike. Just take it slow and gradually. You tried it, knee fussed a bit, you made a good decision to back off a bit, try it again when you think you’re ready, and always listen to the knee. Trying to push the knee further than it’s ready for will just make it rebel, and no one wants that because the knee will always win.
Hang in there, you’re doing great!
