My daughter gets a red raised rash on her neck regularly.  Her Ped. Has tracked it since birth. It usually becomes visible before she comes down with something.  All blood work comes back fine.  No red flags.  What could be causing it.  No allergies.
Hi dear, I understand your concern. It can be signed of symbiosis of intestine, sweat rash, sensitive skin. Perform stool analysis to exclude St aureus symbiosis. I suggest - use Sucre, sorbolen, Vaseline total moisture for skin;- in summer season you can use powder. Hope it helps
