Allegra (fexofenadine) is an antihistamine that likely temporarily reduced the inflammation and itching, but it does not treat the underlying cause. Since the bumps have returned, it is best to see a healthcare provider for a proper examination. This could be a very common, easily treatable issue like a mild localized infection or a contact irritation. In the meantime, please gently wash the area with plain warm water, avoid harsh soaps or creams, and keep the area dry.

It sounds like you are experiencing an allergic reaction, likely contact dermatitis from the hair treatment chemicals. Since you have already taken fexofenadine (Allegra), this should help reduce the itching. You can gently wash your scalp and hair with lukewarm water and a mild, fragrance-free shampoo to remove any remaining chemical residue. Applying a cool, damp compress or a mild, over-the-counter hydrocortisone cream to the affected skin can also provide relief. Please avoid scratching to prevent infection. If the rash continues to spread, or if you develop swelling in your face, lips, or have any difficulty breathing, please seek immediate medical attention.

Since this has lasted ten days, it could be triggered by a delayed allergic reaction to a new product (like soap or lotion), a viral infection, or even stress. Because antihistamines like fexofenadine aren't helping, it is best to have a doctor or dermatologist examine your skin. They can provide a precise diagnosis and prescribe targeted treatments, like topical creams, to help you find relief quickly.

Your symptoms could indeed be related to the sudden hormonal changes following your recent surgical abortion, which can trigger temporary hair loss and feeling unusually hot. However, severe itching without a rash that doesn't respond to allergy medicines like cetirizine or Allegra warrants a closer look. Sometimes, this can point to liver, kidney, or thyroid function changes. I highly recommend visiting your doctor for routine blood tests to check these organs and your hormone levels.

Yes, red spots on the legs can sometimes be associated with COVID-19, but they can also stem from circulation issues or other infections. Since fexofenadine (Allegra) did not help, it suggests these spots may not be a simple allergic reaction. I gently recommend having her evaluated by a doctor to find the exact cause before starting any new medications. In the meantime, please keep her comfortable, avoid scratching the area, and monitor her for other symptoms like fever or breathing changes.

For his sore throat, please avoid starting Augmentin Duo 625 (amoxicillin/clavulanate) without a doctor's prescription. Most sore throats are caused by viral infections, and antibiotics will not work against them. Instead, he can try simple remedies like warm salt-water gargles or over-the-counter paracetamol to help ease the pain. Staying hydrated with warm liquids will also help soothe his throat. If his sore throat persists, worsens, or is accompanied by a high fever, please consult a healthcare professional for a proper evaluation.
