I have a red swollen painful rash on both palms of my hands, does not itch but burns and stings.  My daughter contracted it on Thursday - I woke up w/it this past Saturday - mine has gotten progressively worse.  Where it is spreading around the topside of my hand (by my thumbs) is blistering.
Hello, It could be an edematous rash or a Chat Doctor.  I would recommend you to upload the pictures of the affected areas under the premium section of the site so that I can have a clearer picture of the condition and can guide you accordingly. Hope I have answered your query. Let me know if I can assist you further. Take care
