So my son has been getting this on and off for about a year. Took him to gp who said if was nothing to worry about. Fast forward and it's really bothering me that he gets it as he gets patches off it on arms chest and back. Took him to docs today who said she wants to see us back in 3 weeks time. To possibly take bloods it's left me feeling totally anxious and sad. She did say she wasn't concerned and if she was she would be sending him in. But why do I still feel so anxious? Appreciate anyone talking to me.
