Hi sharonlee
I try to maintain a bi-wkly session for myofascial therapy, and a daily 10-15 mins of stretching exercises to my neck and shoulders - in the hope that this will slow down the deteriorating late effects of radiation.
I don't know if by doing these exercises helps in slowing down the late effects - but I do hope that it will halt or slow down the late effects of radiation.
Hope this helps - take care!!
