1. Usually 2 but if walking around or PT 4-5
If your swelling is 'huge' that alone accounts for at lease 4 points of pain on the 1-10 scale. To me, 4-5 is not severe pain.
2. Acetaminophen 325mg 2tablets every 4 hours needed for mild pain - only took 1 325 tab if I took 2 Hydrocodone.
Been rationing my Hydrocodone because I was only prescribed 20 pills).
Hydrocodone-acetaminophen 7.5-325mg ev 4 hours for moderate pain. Max daily 12 tabs
But you're not getting 'mild' pain, are you? And 325mg is such a very small dose as to be hardly worth the effort of swallowing it! If you're going to take it, take an effective dose which is 1,000mgs but don't forget to add in that which you take in the hydrocodone so you don't end up taking more than 4,000mg in any 24hr period.
3. My knee/leg is moderately huge. I’ve never seen it this big before.
As I said above, that's worth at least 4 points of pain.
4. ROM In hospital it was 85/0 yesterday PT measured 80/0
Not surprising given that you are not even two weeks out yet.
5. Icing 5-6 times daily 20 min.
6. Elevating 4-5 times daily, ½ hour
You accomplish little or nothing in 30 minutes. Ice for at least 40-60mins and as many times a day as you can fit in. All day long that you are sitting and doing other things would be good.
Plus, HOW are you elevating? Is it 'toes above nose'? Here's some examples of good and bad ways to elevate
7. Walking inside house at least once an hour. Don’t stand on it too long it gets uncomfortable
Walk in 'as needed' events such as bathroom visits and getting yourself a drink or a snack. Don't just walk for the sake of it.
Ankle pumps 10x of 3 sets -
you only needed to do these when you were immobile. Clearly you are reasonably mobile now so no longer need to do them
Butt clenches 10 sets 2x day -
these are a very strange thing to do for a knee! More appropriate for hips!
Heel slides 3 sets 10 2x day -
I'd stop doing these for a while. They are clearly causing more swelling and therefore retarding your ROM.
My knee feels like it could explode it’s firm skin, not much room in there to bend it.
Yes, clearly you are doing too much - too much walking, too much exercising and not elevating and icing enough. However, it is early days so you must pay more attention to the things I've said.
But I'd agree with Kawo, you don't need to do exercise nor or later. Many of us here never did any exercises though we were reasonably active otherwise with just the usual activities. But if you are concerned about refusing to do therapy, you need to read this
Saying no to therapy - am I allowed to?
