Accidentally gargling with Betadine (povidone-iodine) antiseptic solution and spitting it out is generally not harmful, though it is stronger than the gargle formulation. The 'fuzzy' feeling on your tongue is likely temporary irritation from this higher concentration. I recommend rinsing your mouth thoroughly with plain water and drinking plenty of fluids. This sensation should improve within a day or two. If you experience worsening irritation, swelling, difficulty swallowing, or if you swallowed a significant amount of the solution, please see a doctor.

While Betadine is a good antiseptic, it may not target the specific root cause of your sores, which could be viral, bacterial, or simply a skin irritation. Sometimes, antiseptic use on sensitive skin can even delay healing. I gently recommend stopping the Betadine and seeing a healthcare provider or visiting a clinic. They can easily swab the area to find the exact cause and prescribe the correct, targeted treatment to help you heal quickly and comfortably.

Chronic diarrhea frequently irritates the delicate pelvic skin, causing itching and burning while worsening hemorrhoids. The penile discomfort may stem from shared nerve pathways in the pelvis or localized muscle tension. To find lasting relief, I highly recommend consulting a gastroenterologist to address the underlying cause of the diarrhea, as resolving this often clears up the skin irritation. A urologist can also help evaluate the penile discomfort. Please be reassured that these symptoms are very common and highly treatable once the root cause is identified.

It is very common to experience a lingering scratchy throat and phlegm after a fever, often due to post-nasal drip. Your choice of warm lemon tea is excellent for soothing the throat, and Betadine gargles can help reduce local irritation, though they should only be used for a few days. To help clear the phlegm, try staying highly hydrated and using steam inhalation. Because these symptoms have lasted over two weeks, it is best to see a doctor to ensure there is no lingering secondary infection or allergy.

That remaining pimple-sized nodule is actually quite common and is often just harmless scar tissue or a small amount of residual inflammation from the healing process. Alternatively, if the original mass was a benign cyst, this nodule could be a remnant of the cyst wall. While there is a slight risk of recurrence if a cyst sac is not fully removed, scar tissue itself is completely harmless. I recommend having your doctor take a quick look at your follow-up appointment just to give you peace of mind.

While Betadine (povidone-iodine) is a good antiseptic, it may not target the underlying cause of your sores, and smoking can significantly delay your mouth's natural healing process. Frequent mouth ulcers require a professional look to rule out infections or nutritional deficiencies. Please consult a dentist or doctor. They can properly evaluate the sore and suggest targeted treatments, like protective oral pastes or specific rinses, to help you find lasting relief.
