Apologies if I am panicking but this afternoon a mobile chiropodist visited my mum and while he was at her house I called in. I told him i had a stubborn verruca. He said he would look at it for me and cut a bit of skin and made it bleed. It didn't hurt but he put some acid on top. At the end of the treatment he asked for some boiling water to pour on to his instruments as he had run out of sterilised instruments. I'm now fretting that his hygiene might not be upto scratch as surely pouring boiling water is not enough? Therefore I'm now paranoid that I have put myself at risk of picking something up- hepatitis, HIV etc. Am I unnecessarily worrying?
