INTERTRIGO ARMPIT AS NAMED BY OUR DERMATOLOGIST, MY WIFE IS HAVING SEVERE SKIN RASHES WITH ITCHING AS WELL AS BURNING SENSATION IN ONE SIDE OF HER ARMPIT SINCE MORE THAN 6 MONTHS. I AM UNABLE TO UNDERSTAND WHY THE GIVEN MEDICATIONS ARE NOT WORKING WELL. IS THERE ANY OTHER ISSUE WHICH THE DERMATOLOGIST FAILED  TO DIAGNOSE WELL? IS IT ACTUALLY INTERTRIGO ARMPIT OR CELLULITUS OR HERPES OR A GENERAL FUNGAL INFECTION. ANY SUGGESTIONS, RECOMMDATIONS  OR GUIDANCE IS WELCOMED.🙏

My Aunt has been getting painful sores/ ulcers on her feet, which the doctors have described as diabetic foot. Even though her Sugar levels are under control now, the pain and the sores refuse to go away. Doctor has suggested Lulibet and Sofinax Ointment to be applied 2-3 times a day. She has been applying this Ointment for two weeks, but still there is no improvement. Please suggest.

My mother has red itchy rashes on the skin in winters. With taking citerizins tablet it becomes normal. Whenever she stops taking medicine, it appears again. Also some patches are also there due to itchiness.
