I noticed this on DS toe earlier on (he’s 12 weeks) I phoned the hv who told me to go to the walk in centre. The doctor said she didn’t know what it was and that was it. Her exact words were “you don’t know and I don’t know” No explanation on what it could be. She didn’t even look that closely at it. I literally spoke to her for 2 minutes. Obviously I don’t know better than a doctor and I’m sure he’ll be fine but I’ve come home not feeling very reassured. Any ideas on what could have caused it?
