Denise- I have to second both Wahine and RnR, pleurisy is nothing to mess with- take some time off, visualize the inflammed tissue healing up and you flying thru your training, honestly visualizing what you want now will likely work a lot better than forcing your body to do it at the moment.
Nothing like the power of the mind at a time like this
Just focus that power on healing would ya not on rubbing the heck out of that poor inflammed pleura
