My husband got a bite.it looked like a mosquito bite maybe?! It kinda swallowed up a lil.we put achol on itand neosporian on it.then after a day we noticed a knot like under skin bout 1 in and / ahalf a way from it on middle of back of his neck.we didnt do anything bout in two days its kinda swallowen more and its sore kinda. We was hoping it wasnt anything but maybe a bump trying to form.i put a heating pad and a warm heating pad on his neck.should i be worried or she i elavate is head or leave it flat.in the front he has a. Lemf node that has been seen and had all kinds of test done last year.it all came up non cancerous and they told him he didnt have to get. It took out unless it was bothering him.so he didnt.but i notice its bigger kinda more noticeable. I gave him 2 asprin.what im doin is it ok?
