Sounds like treatment is really rough on you!
Are there types of treatment that your body has handled better? Does your treatment practitioner have a plan in place that supports your kidneys and liver? What do Lyme-literate folks think about
the chest pain - costochondritis, POTS, lung irritation from infections? Have you had an echocardiogram to check on your heart?
Sorry for all the questions at once.
I hope that these next steps go smoothly for you, and I'm glad that you posted. Too many of us know what it's like to be worried about
dying all the time. It's immensely stressful and demoralizing. Wishing you the best.
