Plan:
1/13: Ultrasound, and No Cortisone after all
1/13-1/17: Swim-only
1/18-1/25, start ramping up isometric strength*, add some light water walking, and keep swimming
1/18: 1x, do 10x 10-second zero-pain isometric holds at straight & bent positions, both-legs for symmetry (L-leg first, then R-at same (low) effort)
1/19+: 2x per day, do 15 x 10-second holds, each side separate
1/26 reassess, but generally:
when isometric strength is at max.-effort, no-pain, try hamstring curls on machine, high rep, low weight, increasing only when if can be done with zero-pain.
2/4-2/10: If hamstring is feeling near full strength, try a few short runs?
2/11-2/17: a few 20-60 minute runs?, max intensity 3, trying at least one forest runs.
2/18-19: GA A-event...
Although the GA & FL events can drop off the racing schedule if hamstring isn't ready to race.(or drop to non-Blue, and easy, rehab training run effort, if hamstring is ready for that, but not racing...)
Note
Just got back from the Dr. Nazarian Ultrasound. Generally good news. They were able to localize the pain quite specifically, to the muscle-tendon junction of the Semimembranosus (or was it Semitendinosus?) hamstring. And they didn't see anything wrong with it - which means there is no visible scar tissue, or tear - where visible means about 2mm... It's just a normal 'strain' that needs normal strain treatments - and there's no reason to believe a cortisone shot would do anything to help the recovery (although it would hurt less for a week or so.) Now for some web research on the variety of recommendations for treating such a sprain.
Open questions:
Ibuprofin or not? Hamstring curls, or light walking/jogging? Low-reps, or higher-reps with less weight? Short jogs, or long walks?
I'm still planning on swim only for the next few days, but then I'll probably want to start some walking/short-jogs, and/or hamstring strength...
Swimming 28:38 [1] 0.71 mi (40:19 / mi)
2-week trial membership expires on 1/19, so I'll have to try to switch to the other membership then...
