TEDS are in my protocol for 6 weeks, 24/7. Mine are thigh-high, and I have 2 pair so change/wash them every few days. So far my PT or home nurse have changed them for me, as I live alone. Since I am still icing my leg a lot, that keeps me cooled down. I don't find them too uncomfortable, except the first few days when the swelling was significant. I iced not only the incision area, but also my lower leg, which helped with residual swelling in that area and thus the comfort level. The nurse taught me to put them on inside out, as the elastic is less binding that way. Powder your foot & lower leg, stretch them out, and once you get them over the heel, you can work them up your leg pretty easily. The TEDS on the operative side still has to be rolled below the incision 10 days post-op.
Regarding your being alone during the day - is there a neighbor or schoolgirl in the area who could stop by once a day for a small fee? You will tire quite easily, and having someone who can just swish through the apartment to do a quick pick-up, help with anything you can't do, pick up something at the store, or just give you the reassurance that if you DO need something, someone will be there - I would find that valuable and reassuring. If your BF is a little OCD, and you are already going to have a walker, cane, reacher, pillows, ice bag, water bottle, etc at hand, it might relieve your stress to have someone to help you tidy up before he gets home.
As for your job ... look at it this way, you are starting a new life. New hip, no pain, you'll have time to recover without feeling the pressure to return to an existing job before you are ready, think about what you want to do and maybe take this opportunity to take a slightly different direction in life.
