Hi, Thanks for using HCM.
Foul smelling, yellowish discharge in right ear indicates persistent infection in ear.
If there is a hole in ear drum you should not put hydroperoxide into ear.
you need to get ear discharge
culture, and correct antibiotic treatment.
Once infection is controlled you need to get operated for your ear drum perforation.
Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take
