Taping made a big difference to me when I was going through a really bad pain flare. Not quite sure how my physio knew what to do as it was a bit of trial and error. Have seen some pictures in a book since - think it was on manual lymphatic drainage (MLD) using kinesio tape so might be worth having a look in a few books in a bookshop as a guide or seeing if you could find someone who does MLD in case they know how.
Good luck!
