Slowly, this has got worse and for about a year now, some pain is also there
when lying
down or in the morning. But as soon as I get up and walk, there is no
pain at all and I can run and walk without any difficulties. Stretching exercise appear to ease it. Once I forgot myself and knelt quickly, resulting in collapsing with a severe cramp-like pain throughout my whole body. Recently, I noticed a similar slight pain in my upper left arm.
