Am also looking at buying these patches, will have them in 2 days and will let you know. I have a rotator cuff muscle problem, am using conventional sports physio therapy combined with anti inflamitory drugs, eg ibobrufun, daily stretching excercises, Seems to bve working. I am sceptical about these patches, anything that claims to do as much as they claim makes me doubt a little. Look up rotator cuff muscle on the net/ there is a host of information, good luck, and be patient shoulder injuries take a long time to heal.What about trying indian aryavedic medicine?
