My cat bit me day before yesterday( Thursday night) on the back of my left hand . It bled a little, even tho it was a deep penetration. It is infected.....swollen, red, and sore. I am taking bromeliane to ease inflammation. And topical and internal colloidal silver. It is not worsening, but neither is it improving much.I have an unused Rx of DOXYCYCLINE , is this an appropriate anti-biotic? I do not have liver disease .
