**Please help! Any opinion, advice and treatment reliefs for the rash and itching.**

My 5 year old son returned from his grandparents house last Sunday with a few bumps on his arm. The next morning, I noticed a few more bumps to both his arms. The same evening, we were getting out of the car and there was construction being done on my street earlier and it looked like possible wet concrete between the road and sidewalk. Instead of stepping over it, he jumped right in. I immediately took him in the house and showered him and washed his sneakers and rinsed his clothes out. By Wednesday, the few bumps on his arm became a widespread rash on both his arms and legs. I took him to the pediatrician and explained what I mentioned and she said since I noticed it Sunday it may be an allergic reaction to mosquitos and to apply OTC hydrocortisone. I wasn’t convinced but I continued the hydrocortisone and calamine lotion. The next day (Thursday), I noticed it spread to his ears and lower face. Took him to urgent care and they said it was HFMD. He had contracted that last year and it didn’t present like that, so again I wasn’t convinced. On Friday, I was able to secure an appointment with a pediatric dermatologist. She said it was contact dermatitis and prescribed him a steroid cream-triamcinolone acetonide- and to follow up in a week. Since Friday, I’ve been applying it and it continues to spread. It’s on his cheeks, forehead, lower abdomen and trunk. The medicine doesn’t seem to be giving him much relief. I bought Aveeno colloidal oatmeal bath and vanicream to help relieve his itching but nothing seems to help. I feel so bad for him and just want his skin to go back to normal. I just don’t understand why it’s continually spreading and if it’s truly contact dermatitis. I’ve attached a few pictures but I feel the pictures doesn’t it enough justice, there are so many bumps. I would truly appreciate input on this!
