I have cracked, itchy and swollen foot. Kindly suggest a solution.

Hello doctor,

I am a 64-year-old female. I have an awful cracked, blistered, and swollen foot. I have been going to hot springs and mineral pools for the last three weeks pretty much daily and had itchiness. But in the last few days, it blistered, the skin cracked and wept, and the swelling has affected the foot up to the ankle. I tried tea tree oil ointment and soap as well as lavender, thinking it might be a fungus. I was also sunning. But no improvement. I popped a blister, and the liquid was brownish but clear and did not smell foul. The rash is confined to between the middle three toes. It looks somewhat symmetrical on the top, with weepy blisters on the second and fourth toes, both next to the middle toe. Underneath, the footpad the middle three toes are swollen and itchy. The small and big toes are swollen and painful but not cracked, blistery, or weepy. Please help.

Thank you doctor,

My feet periodically get mealy skin and crack under the toes, but I have never had anything like this. When I was getting a pedicure several years ago, the technician suggested it might be fungus, but I told her it was just how my feet were in the winter when they got sweaty in the shoes.
