On the 10th I started another session, and within 10 minutes the pain returned. I tried to make it an easy workout and limit it to long sets with 12 kg snatches. Six minutes with the left hand was ok, but one minute with the right made me very sore. I stopped, and this time it took more than one NSAID pill to get better.
Now, two weeks after the event the matters are not better. Moderate pain is there most of the time, it gets worse when I move in a certain way or when I sneeze.
Day before yesterday I did some simple lifting - a few sets of light front squats, pull-ups and some KB pullovers, and I am sore. One activity which doesn't aggravate the pain is cycling, and I have been using the bicycle fair bit.
I am planning a complete lay off from kettlebells for the next three weeks. Incidentally, this Thursday I am leaving for holidays. Re-evaluation on return.
