I find that pre dosing with pain meds helps as well as a pocket so as not to swing my arm or a lsing to support but take it out once in a while to get the blood going if you need to and make sure there is no numbness and tingling in your ...light sling...used only for support and to take the weight of your arm off your shoulder.
just some thoughts....and small walks a few times a day may be better....you know how well I do my own pacing....lol like not!@@@
take care,
love and hugs,
Victoria
