I have three lumps on my head one on the left side of my head just near the top of ear which has grown in size, one at the back of my head on the left and right side and they are the size of a 10p coin they are hard to touch and they do hurt a little bit to touch and I haven't had any illnesses for a while. I have had a headache though. Just wondering what they lumps could be please can you help?
