Hi Ready! I took the liberty of reposting this so others can read it. Most of us here don't do well trying to read large blocks of print. I wasn't sure you knew how to edit.....so here goes! 
-----------------------------------------
Thanks to those that replied to my spinal tap dilema! Alittle background info: Once he was dx, he was put on Doxycycline which didn't help because I believe he already had the Lyme for awhile.
Went to a Rheumatologist due to the arthritic symptoms who only looked at the bloodwork which was , we were told (+), and he tried to explain to use why it was (-).
Did every test under the sun and didn't find anything but still wouldn't believe it was LYme. Went to a LLMD in Pa. that I had found on here that others went to.
He treated him with the Rocephin but only 6 weeks. I tried for more but he said if it dind't work the first time it wouldn't work a second.
(I found out later from the nurse that it may have been more of an insurance problem!
Anyway, he did have him on many antibiotics. He did send his blood and urine to Igenex and told us he was highly positive.
For some reason though, he gave up on us. Just kept giving us the impression that he didn't know what else to do.
We saw other rheumatologists after that---bad idea . We gave up for awhile , even though I knew by his syptoms that he had Lyme, especially since it was the only thing that ever came back as positive.
I met this neurologist and questioned his nurse practitioner on whether or not it was worth our time( I was ready to head to CT to find a doctor)
She said if he didn't know what to do he would find us a doc. That is when he did a complete neuro work up and ruled out other causes.
Did the spinal tap and I think we were all excited--how ever so right or wrong that may seem. I believe he may treat him but might try oral antibiotics.
I really do not think they will help at this point . I would like the IV again.
I need to prove my theory! The only thing I succeded in is getting his primary doc to put him on Elavil.
It made him functional. ANy other suggestions would be appreciated. I hope to write a book someday.
