hello i had a small pea sized lump on my arm for around 2 years, i just thought was grissle, untill recently, it started to swell and i eventually got fed up of it and started squeezing it, well today i started to squeeze it again and it burst out with water/white puss, after i squeezed it all out the lump is no longer there but it wont stop bleeding, seems to be alot of blood for such a small thing
