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.

For the first 3 to 5 days, stick to soft, cool foods like yogurt, smoothies (without a straw), applesauce, and lukewarm mashed potatoes. As you feel better, you can gradually reintroduce solid foods. For your prescribed Betadine (povidone-iodine) mouthwash, it is best to mix it with lukewarm water. Water that is too hot or too cold can irritate your sensitive gums, so a comfortable, room-temperature or slightly warm mix is ideal. Remember to rinse very gently without spitting forcefully to protect the healing areas.

Persistent groin itching and swelling could be caused by a fungal infection, like a yeast infection, or a bacterial skin infection. Sometimes, using antiseptics like povidone-iodine (Betadine) can actually irritate sensitive skin further, causing contact dermatitis which worsens the swelling and itching. It could also represent swollen lymph nodes reacting to a local infection. Since these symptoms are worsening, please avoid applying more povidone-iodine. I gently encourage you to consult a healthcare professional. They can examine the area and prescribe the correct treatment, such as an antifungal or antibiotic cream.

The mouth gels and rinses you mentioned?like Candid, Dolo, Kenacort, Betadine, and Hexadine?contain strong active ingredients, including antifungals, steroids, and antiseptics. Overusing these can strip your tongue's protective mucosal barrier, causing chemical irritation that makes the roughness feel worse. I recommend stopping these products to let your delicate tissues rest and heal. Please stay well-hydrated with plain water and consult a dentist or oral medicine specialist. They can examine your tongue, identify the underlying cause, and guide you toward safe, gentle relief.

Using a povidone-iodine (Betadine) gargle will not help your nasal symptoms. Since gargling only reaches the back of your throat, it cannot target the nasal passages where these symptoms originate. Additionally, gargle solutions are formulated differently and are not safe to use in your nose. For relief from sneezing and a runny nose, a gentle saline nasal spray or an oral antihistamine would be much more effective and safer options.

Do not gargle with the Betadine 10% wound solution. This specific formulation is designed only for the skin and is much too strong for the delicate tissues in your mouth and throat. Swallowing even a small amount of this high-strength povidone-iodine can be harmful. For throat irritation, it is much safer to look for a dedicated povidone-iodine gargle, which is diluted to a safe strength of 0.5% to 1%, or simply use warm salt water. Your safety is the priority, so please keep the wound cleaner for external skin use only.
