I've had both done. The consultant told me they no longer do both hands at the same time (for obvious reasons!) I chose to have my right hand done first as I am right-handed so it was more important (just in case it was so awful that I couldn't go through it a 2nd time!!). It was fine! I didn't need painkillers at all afterwards and could use my hand, generally, a couple of days later - not for wringing out cloths, opening jars etc, that took a couple of weeks! Do ensure you have loose pull-up trousers, no bra, no buttons, zips etc. When I had the left hand done, it was a different story - I needed painkillers as it was a lot more painful for the next 48 hours and it didn't heel anywhere near as quickly. When I went to my follow-up appointment, I asked the consultant why the difference. Was it because my right hand was 'stronger' being the main hand? Was it because I'd been through a lot of stress (not connected) between the two operations? Was it because the 2nd hand has already suffered the trauma of the 1st?!! He said in his experience, one hand always seems to deal with it better but studies showed no specific reason, it appears to be random! That said, it has made such a difference to my life, and that bit of pain and inconvenience was more than worth it. It's great if you can help her in the first day or two, but as she has young children, help would be great for longer, as young children are not considerate!! I prepared a load of meals in advance and put in the freezer so meals were much easier, I used plastic bags on my hand to stop them getting wet, I did all the cleaning etc just before, so I didn't feel I had to attempt any of that, and all in all, I made sure I had a lazy few days. She doesn't need to keep the sling on for more than a day or two, but there again, a sling is a visual reminder to others that she may not be able to do lots of things! (It's tempting to keep it on for at least a couple of weeks, to get as much help (and sympathy!!) as possible!!
