Hard tender lump on my head?!
I have had a very hard, tender lump on my head for 3 days. It is on the left side, directly above the occipital area. It is quite sore and extremely tender to the touch - it feels like it is bruised. Thelump would be about one inch in diameter, and slightly raised.
I am not unwell at all, so I am not sure if it would be a swollen lymph node due to infection?
It is rock hard, and just feels like bone, except sore!
I am aware I can not get a diagnosis here, but I would like to know what it is likely to be and how long I should I wait to see if it goes away before I make an appointment with my GP?
