Headaches at back of head and neck upon awakening...what does this sound like?

What does this sound like to you?

My 4 year old son is currently being treated for lyme but has tested negative for all of the coinfections.

We think he may possibly have bart so he is taking omnicef and bactrim. He has improved somewhat after 5 months of treatment, but now when I check him at 10 pm after he has been sleeping for 2 hours, his pillow is wet from him sweating. Normally his pj's are not wet; just his head and pillow.

This just started happening after 4 months of treatment.

Today when he woke up he was grumpy and when I asked if anything hurt, he said that the back of his head and neck hurt. about an hour later when I asked him, he said nothing hurt, so it apparently went away.

I am trying to figure out if he has babs or not. He has the sweating and occasional headache, but not the other symptoms such as fatigue and loss of appetite. This makes me wonder if perhaps the sweating is from the bart.

My other 4 year old does in fact have babesia (positive Igenex FISH test) and he was sweating the same way at night but to an even greater extent. His sweating is gone now after a month of treatment. He also had severe fatigue and loss of appetite, which has improved with treatment.

Do you think this could be babesia?

Are the babesia tests just as unreliable as the lyme tests?

Has anyone tested positive for babesia with so few typical babesia symptoms?

If you have babesia, are your headaches at the back of your head and neck? Do you have them daily or on and off?

Thanks for your input!
