First off, sadly, my flight was cancelled because of the storms in the northeast. All later flights were booked for three day so I am not going until Sunday. Luckily I was able to extend three days on the other end without penalty so I will only have one day less with my daughter and grandson. I cried as I watched the flights disappearing on my computer while I was on hold with the reservation clerk, but it all worked out.
Also: for those who were following my bathtub saga, I did it today!

My leg (5 days post-treadmill incident) was driving me crazy this morning and I decided today was the day for the Epsom Salt bath. I bought a new garden kneeler which I used to get in and out. It was still awkward because my legs are long and the tub is narrow, but I safely put one knee on the pad in the tub and was able to get in with only slight discomfort in my "good" knee. And it was worth it. It was so relaxing and my knee felt great in the water. My dad swore by Epsom salts and it sure felt good to me, too. Of course, Hubby was standing by in the next room in case I needed help. Safety first!
@KarriB, I imagine you are right about the treadmill. My husband wonders if it is the "bounce" of the treadmill and that it is a steady pace (though I do change the speed throughout) that are the problems. I loved my treadmill before my knees started acting up. It faces the garden and I put music on to block out the world and could feel my legs getting stronger (they used to be my strongest part!). And, I like watching the numbers. Gratifying! I haven't been using it much since surgery but have been running errands that add up to about 3-4000 steps a day - and have been doing the water exercise classes 2-3 days a week. I'd had to miss my classes due to family obligations and it was pouring and I was waiting for a repairman - so not a normal situation and I thought since my pedometer indicates I walk much farther regularly - a mile would be OK. Just wrong and I won't be doing it again soon. The bike bothers my "good" knee across the top and the IT band. That knee also needs repair. Since my thyroid remains in flux, I will not be having it done anytime soon. I may need to have my thyroid "killed" with radioactive iodine depending on whether it continues to bounce around from hyper to hypo and back.
@SusieShoes , of course you are right, too. Walking outdoors is wonderful when it is a pretty area at least. I don't like the mall. Everyone is walking slower than I am and I feel closed in. The movement outside is varied and I'm more likely to stop to rest (if there is a place to do so). My town is flat - the whole thing - so no changes in elevation except stepping off the curb or climbing some stairs. Also, its too hot to walk in the summer and foggy in the winter with not much to see. It's been the convenience of having the treadmill and bike at home and the time factor that always kept me active before surgery. For now I don't like to get too far from home on foot as I can't easily judge how much my legs will cooperate on any given day.
It does seem strange that it is now five days since my treadmill incident and I am still having trouble. The knee feels, but is not swollen and "gives" sometimes when I am walking. I had given up the cane two or three weeks ago and had to use it when I went out to Lowe's this week. As Susie said, I am frustrated. In September I was taking a 3 mile hike on the coast and now I can't imagine doing that. I have to accept that it will be several more weeks most likely before the strength is back. I am planning on taking my 3 year old grandson to Disneyland in June, regardless. I will get a wheelchair if I need to because I am not going to miss any more of his growing up than I have to.
Thanks everyone for your kindness and suggestions. Sorry this is so long. I obviously have too much time on my hands. Will likely spend the afternoon with a book and leg elevated. I have four days to get this knee in good enough shape for a six hour flight and a trudge through two airports.
