Rather specific query I know. 3yo DS has chickenpox, started at the weekend. I noticed yesterday he has a big lump directly behind his left ear. Not right behind the lobe but higher up on the bony part IYKWIM. It seems tender but is hard.
DH thinks it is in the area of his mastoid ( DH has had lots of mastoid problems and operations and suffered significant hearing loss as a result). Do I need to be concerned? I wasn't planning on taking him to the GP as he is fine in himself and I am sure it's CPox (recent exposure and I'm a nurse but know little about ears!)
Is it probably just a swollen gland due to the virus? TIA
