Need help

Your symptoms sound like they are perfectly in line with a very early stage lyme infection. If your treatment started soon after your infection (sounds like yours did) and you're only one week into treatment then there's no reason to get all worried yet. Just continue to take your medication as it was written and you should start to feel better soon; there would be no reason to change from doxy at this point. Ideally you would get at least a full 4 weeks of treatment, but even if they went really conservative and you only got 2 weeks you still have an excellent chance at a full recovery (again, assuming you started treatment soon after the infection).

If you start to experience significant neurological symptoms (burning, tingling, muscle twitches, facial numbness, loss of muscle control, etc) you should probably get right back to the doctor, but otherwise just ride it out and pay close attention to your symptoms. If you still have significant symptoms after your treatment ends, or symptoms come back shortly after you stop treatment, then you can start looking into treatment with a specialist.

I would continue to look for a LLMD though. Even for an early case. Try the LDA website.

Many LLMD's believe that doxy @ 200mg is NOT effective as it only addresses the spirochete form. It doesn't address the cystic form or the cell wall deficient. It also doesn't cure babesia, bartonella or many other co-infections that are very common to contract even from a single tick bite. There are studies that suggests low dose doxy by itself increases lyme cysts by 200%.

If it were me, having had serious complications from not treating Lyme when it was in the acute stage, I would want doxy 400mg, zithromax and flagyl or tindamax. I would line up a LLMD to make sure you get aggressive treatment now before things have a chance to progress. Most likely a regular doctor will not give you more than 4 weeks of doxy and will not dose over 200mg per day.
