The arm’s doing better, the doc encouraged me not to keep it in the sling all the time, except if it’s hurting a lot, but rather to try to start using it, flexing it, and carefully stretching it so it doesn’t get tight. With Ibuprofen, it doesn’t hurt generally, unless I try to do something strenuous, like use a mouse. Typing is mostly one-handed.

Thanks to everyone for the concern! Thank God it wasn’t broken. It sure felt like it at the time.
