After a couple of weeks with only limited weight training, the tendons have been pain free, and there was no clicking when raising the arm. But I have to improve the strength. It seems that the problems are aggravated by heavy weights, so I'll go back to my 8 pounders and elementary exercises such as simply raising the straight arm in different angles and low impact cable column exercises. I have also discovered the pec fly/rear delt machine at the gym. It gives a wonderful stretch in the pec fly position.
