My sisters little toe has grown a purple bump with a hole in it!!! any help?! She says it doesnt hurt. She says she got a needle stuck in it and just left it alone. My cat has fleas that have multiplied din my home and she is dumb enough to scratch..and has nasty scars. We are afraid to take her to the doctor they might think she is being abused,and they might try forcing something out of her. so please any hel[p?? or will they leave her alone about her flea bites and focus on her swelling???
