Can BV cause sores

The first time I got BV I got really painful sores a few days after I started getting all the other common symptoms of BV.

I have sores again and some symptoms of BV. I tested negative for herpes and my partner at the time Also tested negative. The doctor gave me BV medication such as Vandazole and everytning including the sores cleared up before I finished the full round.

Im really confused but everything I google leads me back to herpes.
