Lymphodema says you have blockage in your system. Besides parasites you probably need to get tons of detox to get things flowing. Bowel Cleanse, liver cleanse, Lymph, kidneys. These systems are synegystic, they all work together. If one of them has blocked there is blockage elsewhere. They must be running clean and clear. Do some searches on these. Also Dr Sutton forum has some information. Dr Sutton Cured himself of liver cancer after Vietnam. (youtube video -The medical paradym) and Dr Majid Ali videos on castor oil and lympth system).
Sometimes you can think the bowels is open but it could have old furniture strewn all along the side of the road. I am not a big person but I saw rubber tires, tree barks, junk come out after using sonnie bowel cleanse. (just kidding:) I wondered where the heck all this stuff was being stored at.
They say you gotto open your detox and healing pathways. If there is a traffic jam, and you take meds to kill parasites, may be creating a back up in your system. Since the body may be having a problem disposing of the debris efficiently. This just my opinion, readings and summizations of how the body works, since I am not a med.
