Stretching exercises for shoulder and elbow pain are generally held for 30 to 60 seconds. Performing two to five repetitions is usually all that's needed to experience a positive effect. During the first week, I typically ask my clients to commit to performing their stretches as often as possible (two to five times each day) to aggressively reduce their symptoms.
It should always feel good to perform the stretching exercises, so this really shouldn't be a hard sell. After the first week, when your symptoms have abated, you can ease off and find the ideal number of times needed to keep your pain at bay. I recommend doing the exercises first thing in the morning and last thing before bed as most people's pain becomes aggravated during sleep.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
