Hi wednesdayblue. I like your name.
Yes, its true that testing for Lyme is very unreliable. I tested negative a few times which wasted months of my time running after misdiagnoses.
Once I saw a Lyme Literate Medical Doctor (LLMD), I began treatment before my blood test results came back from Igenex.
Unfortunately the list of symptoms for Lyme is long and you can have some or all of them. There's a sticky post at the top of this board for the list. You may want to check it out. Lyme can affect blood count.
I had my blood sent to a lab called Igenex in Palo Alto CA. You can visit their web site and even order the blood test stuff right there. A doctor, of course, has to draw the blood and mail it to them.
Lastly, ten days is not long enough to treat a Lyme infection, even if its caught quickly like yours. You need to be on medicine for a long period of time.
There is good news - Lyme is curable and you will feel better someday.
If you post your state and town, maybe someone can suggest a good LLMD for you to see.
Hang in there and try not to worry. Ok?
Peace and health to you.
