reoccuring bruise

about a month ago over a couple of day my big toe, left foot became discolored then blueish and finally it was a horrible black...soaked it in white vinegar and epsom salt... it was a little pus and the nail lifted...pressed and it drained ...soaked it the next day and drained a little more...the nailed came off and has started to grow back...i noticed yesterday its getting discolored again down near the cuticle and there is soreness...i dont remember bumping it the first time or now and have been wearing flip flop since...

Hi,
Sounds like it is probably getting infected again. Your best bet would be to see a podiatrist and have the toe properly cared for.
