The burning sensation and reduced sense of smell are likely due to the viral infection itself causing inflammation in your nasal passages, rather than the Vicks Action 500, though oral decongestants like phenylephrine can sometimes cause mild dryness. To help soothe your nose, try using a simple saline nasal spray and steam inhalation to restore moisture. This should gradually improve as your body recovers from the cold. However, if these symptoms persist past a week or worsen, please consult a healthcare professional for a gentle evaluation.

Since you have completed your five-day course of ivermectin and azithromycin, you should stop taking them. For your remaining mild cough, plain steam inhalation is highly effective and gentler on your airways than adding Vicks or Karvol. You can take paracetamol as needed for discomfort, ensuring you do not exceed 3,000 mg in 24 hours. Most importantly, please consult your doctor promptly regarding your elevated blood sugar and inflammation levels, as these require close medical supervision and tailored management. Rest well, stay hydrated.

For a one-year-old, the safest way to clear a runny nose is using saline nasal drops and gently suctioning with a bulb syringe. A cool-mist humidifier in his room is much safer than hot steam, which carries a burn risk. Please do not use Vicks VapoRub on him, as it is unsafe for children under two. For his headache or discomfort, you can consult his pediatrician for the correct dose of infant acetaminophen or ibuprofen. Keep him hydrated and cozy, and always reach out to his doctor if his symptoms worsen.

To help him feel more comfortable, please stick to plain, warm water steam inhalation. Adding medicated ointments like Vicks is not recommended, as strong vapors can further irritate inflamed airways. Keeping him hydrated with warm fluids and offering small, frequent meals will help support his strength and appetite. Because sudden lung inflammation, loss of taste, and weakness require careful evaluation, please consult a healthcare provider promptly to get a precise diagnosis and safe, targeted prescription treatments.

But please be reassured that losing your sense of taste and smell after a cold is very common and usually temporary, not permanent or serious. It typically improves gradually over a few weeks. Since you used Vicks VapoRub, just ensure it is applied only to your chest or throat, and never inside your nostrils. To help your recovery, you can try 'olfactory training' at home. Gently sniff strong, familiar scents like lemon, eucalyptus, cloves, or rose for about 20 seconds each, twice a day. This helps stimulate your nasal nerves. Stay well-hydrated, and give your body some time to heal.

Yes, it is completely normal to experience localized itching, redness, or swelling at the injection site 48 hours after a tetanus vaccine. This mild reaction is common and safe during pregnancy. If standard topical remedies haven't helped, applying a cold compress for 15 minutes can soothe the area. For persistent itching, oral antihistamines like cetirizine are generally considered safe during pregnancy, but please consult your obstetrician or midwife before taking any oral medications to ensure they are safe for your specific pregnancy. Try to avoid scratching to prevent infection.
