Thank you. I contacted my doctor and have an apt tomorrow.
Hello,
From the symptoms, it can be contact dermatitis , allergic reaction, friction blisters, bullous staph infection or pompholyx. Wear shoes that fit properly and keep feet as dry as possible. Wearing wet shoes, boots and socks will increase your chance of developing blisters. So change socks regularly. Also take antihistaminic like Benadryl or Claritin if the lesions are itchy.
And use foot powder to help keep your feet dry. If the blisters still persist then please get it evaluated from a dermatologist/podiatrist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thank you so much for your help. I will keep them dry and clean.
