Hi everyone hope all is well ️
last year in summer my little boy bought home head lice from school and I was unfortunate to catch them of him . I have never had them before so I panicked treated my hair with many products by the looks of it it looks like I have burned my scalp all was good thought until last month I've bought cheap shampoo because it was on offer for 25p and I find that my scalp has became very itchy burning sensation and I've started to get dandruff that's when I've touched back of my 

neck and found more of a bump that is rubbery feels spongy when I press it but doesn't move under the skin I've been to doctors and they have said it does feel like swollen lymph node ( 3 different doctors ) has prescribed me anti fungal shampoo but week on the lump is still there not getting any smaller or bigger I keep touching it because I am so worried

i also have snotty nose the odd cough no bumps or lumps anywhere else ... anyone in similar situation please thank you
