Hello,
Rashes on the palms with itching is commonly due to warm humid weather, seasonal allergies, sweaty or wet hands and feet, coming in contact with some contagious substance,
allergy due to contact with cosmetic jewellery, contact with metals like nickels, cobalt, chromium,
stress, etc. To avoid getting it spread do not touch the blisters, do not scratch or pick.
Use gloves with cotton liners. before washing your hands take your rings off your fingers. Use a humidifier if weather is too dry to stop your skin from cracking. Apply Dimethicone cream to protect your skin.
Hydrocortisone creams and
ointments also work well. Take non sedating antihistamines, once daily for 3-5 days for relief.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
