Homeopathic treatment is probably the least expensive. There is a product called "Acute ViroReliever" (but it helps other kinds of infections as well) that I'm taking (prescribed by my LL Naturopath) that I have to take less often than daily because otherwise I herx...so I know it is helping to boost the health of my immune system. The same company (King Bio) makes another product called "Lyme Plex" that is for fever, joint & muscle pain, skin rashes, etc., that may help too. Each product costs about $20 (+ sales tax & shipping) but lasts a while because of the fine mist spray (both products are water-based homeopathics, no alcohol or preservatives). Because King Bio is a registered FDA-approved pharmaceutical company, your regular doctor may be able to prescribe these products (or other applicable products) for you and order them for you (or he may do so thorugh a natural health or compounding pharmacy) -- if your doctor is open to trying non-traditional things that may help you.
