Result: Painless steroid injection, which may cause improvement by the wknd. As an experienced cynic, I'm not holding my breath.
Other notes: Diagnosis (Efficient: 45 min. in the room, diagnosis to treatment.) by "sports doctor" took place downtown, fortunately w/in easy limping distance of the
Red/Purple B/D Line. While I was nervous about riding in an enclosed tube w/ zillions of plague germs & the germbags carrying them (busses have been about as crowded as pre-plague) the train was virtually empty both ways, no more than eight or ten germbags per car, possibly due to the recently strengthened stay-in-your-homes rules. Which did lead to having to stand in line at a Ralphs for a few mins. before being let in. Nicely uncrowded once inside. Seems like a good idea even if the plague does disappear.
