This morning I noticed a lump at the bottom of my head on the right side. It is slightly painful (probably a 2 on a scale of 1-10) and Im lightheaded/dizzy.  I fell on my back last weekend, but dont think I hit my head.  This week I was sick with the cold that everyone is getting, but havent taken any medication today. Should I get this checked or give it a couple of days to see if it goes away?
Hello, I understand your lump which is there only since this morning, has appeared somewhere behind the ear on right side? Not sure though. Any ways, if it's paining and making you feel dizzy, I suggest that you consult your doctor and start on antibiotics if advised. Generally suddenly appearing painful lumps indicate infections and must not be neglected else they can get severe. Hope this helps.
