Have yo done any lymph massages on that area? I have lymph swelling a lot when I'm fighting these infections, as it's the first "filter" of the bloodstream, so they get "clogged" from time to time.
Here's a good 'how to' video on lymph massages if you need to see one - although you only want to do the massages until your lymph node is a little sore - and don't use much pressure at all. If you can only rub them for, say 1 minute and need to stop, then stop - just be sure to rub on them whenever you think of it and remember, very little pressure, as you are only trying to stimulate them to keep moving. /www.youtube.com/watch?v=QA-wi0d7-Ro
