I recently started taking trellegy for long haul covid. i think i may have a yeast infection now because i have irritation on my penis, under the tip. also seems to be itchy around the top. not bad, but dont want to be worse. i have tried cortisone?

Self diagnosis is most always wrong. Does not sound like an yeast infection. Wash the area with soap and water and apply benadryl cream/ointment. If not better pl see your doc or Urologist. Hope you feel better

I agree it's best to have an accurate diagnosis with proper treatment. You may be correct in your diagnosis and, if you wish, you could first try applying a nonprescription antiyeast cream. Bear in mind that yeast infections can be passed back and forth between sexual partners. Both would need treatment.
