I was diagnosed with Ehrliciosis 7 weeks ago and put on Doxycyclin pretty much right away. I took it for two weeks, then thought that was it - I was supposed to be better - had two and a half weeks without it then my hands froze up and I was back in the ER and they put me back on Doxycyclin. I am tired, I can't concentrate and my family is dependent on my income - I am a writer.
