over a few days of intense pain blood appeared under the big toe nail. i did not injure the toe but i was on my feet alot that week. it still throbs on and off. the nail may be infected with a fungal infection as it was slightly yellow. i also developed a pea sized lump under my middle toe on same foot 2 mts previously. its not painful so i ignored it not sure if the 2 are related. any thoughts any one?
