A very friendly doctor stabbed a needle into the muscle this morning and then pressed some of the good juice in. She also did it so gently and carefully that I felt about... nothing. I've actually felt more when grasses rubbed my skin with their prickly ends - not to speak at all about a midge bite, or scratchy madder plants, which both have been able to draw blood.
So... I will gladly forego bouldering for the next two days due to this (no sports for two days, she said). The second shot will be in six weeks' time, which means it's just in time for the full protection to be in place for the Textile Forum.
Whew.
