Hello. Last month my HIV positive mother-in-law visited for a couple of weeks. When I shave my legs, I usually sit on the edge of the bath and use the water that runs down the bottom of the bath tube when rinsing the razor. If she took a shower immediately before me and I shaved my legs, rinsing the blade on the water running down the bath floor, could I have gotten infected if I nicked myself. The reason I am concerned is because about a week after she left I got sick with a runny nose, congestion, and a dry cough that lasted for about 10 days (felt like a typical head cold). I also got a canker sore (although I have gotten them my whole life). I don't want to discuss this with my husband since he already is sensitive about his mom's condition and he would think I was overreacting. Thoughts? Thanks. Sorry if this is an irrational fear.
