If you are lucky, you may get IV antibiotics for up to a month. It depends on where you live and how understanding your doctor is. Lyme is often referred to as a 'rich persons disease'. Believe me, nothing is worse than having chronic Lyme, being refused adequate treatment by your doctor and not having enough money to fund private treatment. One visit can cost hundreds if not thousands, IF you are lucky enough to find a LLMD (Lyme Literate Medical Doctor). In the US, it's hard, but in the UK it is IMPOSSIBLE to find an LLMD that the GMC (General Medical Council) have not tried to destroy. You can (if you're feeling brave) self-treat. There are many reputable online pharmacies that you can purchase antibiotics from, if that's the route that you chose to take.
