Does lyme disease and co infections increase the risk of blood clots? and if so by how much? i take 3000 mg fishoil a day would that prevent issues?

Definitely not: Lyme disease and other tick borne illnesses should not increase the risk for blood clots. See a hematologist if you suffer from clots. There are things that CAN be done - like no smoking, avoiding birth control pills (estrogens), avoiding long stationary periods (sitting on a plane), avoiding injury to legs/veins, etc. Fish oil is a supplement - probably won't help this situation at all. See an MD
