Hi welcome to health care magic... According to history you can have impacted wax or secondary otitis externa like infection... Your right ear Otoscopy examination is needed here.. If wax there than removed with suction or syringing... Antibiotic ear drop prescribed that is used four times a day.... Glycerine coated cotton may be put in ear for one day to reduce swelling of ear canal. If Otoscopy suggest toward fungal growth than treatment different with antifungal and gention violet Hope this will help Consult otorhinolaryngologist and discuss these points.
