Congestion With Lyme Disease

During my latest treatment, I have had an ear ache, swollen lymph nodes behind my ear, congestion, and sore throat.  Is this a new manifestation of Lyme, Bartonella, or Babesia?  I have no way of knowing the answer to that question, but I found a way to help the congestion and coughing through an old folk remedy:\

I have also read about putting raw onions in your socks over night to get relief from infections.  I asked a friend who is a bio-medical chemist, why this might work.  He said that it most likely is because the onions contain sulfur, which could be absorbed through your feet.

I am intrigued by folk remedies that seem to work as well as prescription medicine.  Most cost very little and are usually cures that someone might already have around the house.  I am sure that there are other folk remedies that Lyme patients could recommend.
