I got a walker, a commode chair, and a shower chair from the thrift store for my husband when he had hip surgery. All for less than $35. His insurance would have paid for new stuff, but I think it is kind of dumb, rather wasteful. I just donated them back when he was done with them.
A friend of mine has had several knee surgeries, and has multiples of the above in her shed. She gets new ones every time she has surgery.
I use distraction like you suggested, along with adequate medication to manage my pain. I may have some pain, but it is managable. I use opiates and neurontin and a sleep aid. Works for me, most of the time.
I read an article in our local newspaper a few years back that said our state was one of seven states that did not specify what drugs you could or could not take for a DUI, the officer just has to decide if you are impaired or not. So, even if you are wasted on an OTC antihistamine, the officer can decide you are impaired, and give you a ticket. A blood test or breathalizer taken at the time of the ticket can give them more info, but the officer's word is enough for a ticket to be issued. You can argue about it in court.
