hi,
It may be a good idea as (broken wings) has suggested. If it is lymph accumulation then it could help to decrease the size of it. It that doesn't help get a doctor who is willing to actually take you seriously....sorry .....are there any left! Considering what you have been through!!!
Lungs???? I can see if you have shortness of breath or some other lung issue like a barrel chest or something to suggest you have a breathing problem!!
Any old excuse to get you the hell out the door incase they have to actually work you up....hmmm lets just take the money and run!!!

Sorry feeling a little cynical.
I really do suggest that you try massage on one of your days..if you know a good one or have one..make sure if you don't have one to get a good recommendation from someone as there are a lot of crappy ones...no offense but I have had my share to get to good ones!!

hope some of that helps.
take care,
Love and Hugs,
Victoria
