I am a 25 year old female. Ok, I was wearing flip flops when I entered a public restroom last night and the floor was all covered with wetness as though the toilet had backed up or something...just really disgusting. When I walked in I tried to be careful as not to let any of the fluids form the floor (which I would imagine to be a mix of toilet water and urine) touch my feet. When I returned home later ( this is weird and gross I know) I was in pain from a very slight ingrown nail I had noticed throughout the evening and could not find my nail clippers anywhere so I decided the only way to fix it would be to use my teeth to try to cut the nail a bit- in doing this I cut my tongue on my nail and made it bleed....now I am very concerned. This was at least 20 minutes after I had left the bathroom- and as far as I remember my feet never became wet themselves from the bathroom water ( unless some splashed without my noticing) but now I am very afraid of contracting hiv this way.....what do you think?
