Double the bad

I was tired and sleepy quite a lot of the past week, though I'm not certain why, as I was during the days even when I had slept well. Monday's iaido practice I got through on pure will, I had such an incredibly hard time concentrating! My thoughts ran away all over the place. It got better as time went, though in the end it became hard to keep again. Especially when my shoulder started acting up some more...
Which, by the way, ties in with Wednesday's practice. I don't know what I did, but I pulled at one of the ties of the only other participant's hakama (a beginner, whom I caught just before he left, as I was a wee bit late and it was a holiday so people turned back home when there wasn't anyone there on time - anyway, I showed him the way of tying your hakama) something felt like it tore in my left shoulder. I could do iaido, after some warmup and cautious stretching, but it hurt, and still does. I'm treating it as best I can with salves with Arnica in, and liniment, and Voltarol with diclofenac (spelling?). Occasionally drawbacks happen - nearly fell on the train and reflexively caught myself with the left arm, which hurt, and I have had to carry heavy things, which also made it worse... and so on.

It drives me a little mad, because it feels like I've almost lost the use of both my arms now. I don't know what to do if a doctor orders me to rest for more than about a week... and I know that my right shoulder didn't exactly get better even after half a year of rest. The pain isn't exactly identical though, giving me hope that the one in the left shoulder might just be a bit of a strain on some piece of the muscle connection to the bone or such.

Because of this injury, Thursday's Kali practice was also a bit more painful and less fun than I had hoped. Some movements with raised arms made the left shoulder hurt worse. I'm debating whether I should push and do some physical therapy exercises, or just leave it to rest as much as possible before the National Championships. I'm leaning towards the former. What do you think?
I do at least feel like I'm getting back my zanshin and correct "mind of iai", and am able to project a powerful fighting spirit again.

Since I was away over the weekend, this post is late. I don't mind however as I managed to go for a run in the perfect weather, with the calm sea beside and below me, and the beginnings of flowers and grass smelling sweet. I went only for fifteen minutes, again, to be careful with my legs. I've had no trouble today though, and my knees feel fine (though the left one's been acting up for a month or so!), so maybe I'll dare start running in the mornings soon? I'm not a morning person but having some zazen and a run to look forward to maybe it'll be easier to get up.
