I used 2 different 'things' and not sure which worked but one sure did! One is the Dr. Vodder method of massage for the lymph glands. I'm no expert and have only done this on myself i.e. no professional help. Look up "vodder massage" on the net or youtube. You have to gently massage the lymph gland at the top of your leg then softly massage from that area down to the swelling. The other is the use of Arnica ointment. I put this on at night, massaged a bit then slept with kitchen plastic wrap around the area, as it says on the jar. Next day -:th_heehee: much less swelling! I think it may be the arnica but have not done a "do one only" type check. Re my 'dreaded tightness under the knees' - it is still there but my Specialist answered my email to say to use ice on it daily.....and to come back after 3 months if it is still there! Do hope this info is a help to many of you. Sorry it is not definative or professional.
