Hello, Tuesday 29th July I hit my head and was unconscious for about 2/3 minutes... Managed to get a horrible cold the next day and a week later I ve come up with a hard lump on my mastoid process (slightly above my earlobe) and the area just above the lump is tender.
Welcome to Chat Doctor .1. The possible cause of the lump could be subbed cutaneous / intro muscular hematoma. 2. Loss of consciousness is serious issue, in your case I would have asked for a CT best to find out ant intracranial involvement, bony injury.3. For symptomatic you can use the painkiller cream and there are thrombolytic superficial applicable creams - but needs to get proscribed from your GP.4. See for a day or two - if resolving then fine, If not then you have to get an appointment and get the needful tests and treatment done. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
