<s>[INST] My 4 year old son has a cracked lip, a red blotchy rash from ankles to his feet and it goes up his leg. The rash is also around his wrists. He doesn t have a fever. The rash is not raised nor is it hot. The rash does not itch. We gave 1 tsp of benadryl and rash is still there. [/INST] Hi... I feel by what you quote he should be having a - Hand Foot Mouth disease. This is one viral illness among all other anthems which can cause fever followed by rash over palms and soles. It is a self-limiting disorder and itching can be really worrisome. I suggest you use any over the counter antihistamine if you have one with you now. You can use HY Chat Doctor.  This can even cause some peeling of skin in the next 4-6 weeks and do not worry about it. Regards -  </s>
