What causes recurrent itchy blisters on the toes and feet?
Patient: Good morning...My name is Heather & I am trying to help someone very near & dear to my heart figure out what might be causing some issues they are experiencing...Hopefully you can be of some assistance...for over a year now, they have had reoccurring episodes (every 2 months or so) of tiny, extremely itchy blister like rashes on the exterior of his heels, also on the outer edges of the soles of his feet but not underneath on the bottom of the soles & between his toes on both feet, on the upper buttocks (above & slightly down into his butt crack) & in his upper groin/pelvic region...he complains that the itch is almost unbearable & when I observed these areas he had scratched them so much that it s caused some scabbing...when popped, the tiny blisters release a clear fluid/pus...we ve tried so many different things such as creams & lotions with no real results...like I said these episodes have been reoccurring for some time now & we have racked our brains trying to figure out what might be causing their on-set but again are dumb-founded...I should inform you that he has been regularly checked for STD s & ALL tests have come back negative...in the past he had tested positive for H-Pyloria but was successfully treated...any help or insight into this bizarre nightmare would be greatly appreciated!...a little more information on him...Black/Hispanic male...50 years old...good health...takes anti-anxiety & acid reflux medications daily...never has been a drinker, drug user or smoker... Doctor: Hi,  Your near and dear fellow may be having dermatitis herpetiformis most probably. However, you consult the dermatologist for the confirmation of diagnosis.  You may give him Dapsone thrice a day till he gets relief. And you may add cetirizine 10 mg daily at night.   Apply antibiotic cream to prevent secondary bacterial infection.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Ilyas Patel, Dermatologist
