Hi, I returned from Thailand 10 days ago and I still have a rash all over my back. They are small bumps and not as itchy as they used to be. I did have itchy rash on neck and chest but that is not as bad now. I am a 30 year old female, 169cm tall and weigh 59kgs.
Hello, I read carefully your query and understand your concern. The symptoms seem to be related to contact dermatitis. I suggest using Cetirizine 10 mg daily. I also suggest using HY Chat Doctor.  Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!
