Treatment for Lyme simply won't clear a Bartonella infection. They need different abx, if I'm thinking clearly, which may not be the case. Lol. I just got back from a long weekend away. Lol.
Swollen lymph nodes could be nothing more than them being "congested", full of "debris". The lymph nodes "job" is as the first filter of the blood, removing DNA particles and such, so they can often become swollen and possibly painful (but not always) when we have infections.
Lymph massages work well to heal this. This is a good video of how to do a lymph massage, but I think she says to do it 50 times - which we should not be doing. Only do the massage until you get some relief or the lymph nodes becomes sore. You can do them several times a day though to help move along the process of filtering the blood, so it can go on to the next stage of filtering through other organs.
