Your symptoms are very classic for scabies, which is why standard antihistamines and antiseptics haven't provided relief. Please reassure yourself that this is common and highly treatable. The most effective treatments are prescription-strength medications, specifically a topical cream called permethrin, applied from the neck down overnight, or an oral prescription called ivermectin. Because scabies spreads easily, household contacts should be treated at the same time, and bedding should be washed in hot water. Please consult a healthcare provider to get the right prescription so you can finally get some comfortable sleep.

Since the injections of Avil (pheniramine) and Deca (dexamethasone) have not fully resolved your reaction, I highly recommend consulting your doctor or visiting an urgent care clinic promptly for a re-evaluation. They can safely adjust your treatment. In the meantime, try applying cool compresses and wear loose clothing to soothe your skin. Please avoid scratching to prevent infection. Most importantly, if you develop any difficulty breathing, swelling of your face or throat, or dizziness, please seek emergency medical care immediately.

Oral pheniramine, which you mentioned as Avil, is an antihistamine. It is very helpful if your reaction to the aloe vera involves itching, redness, or hives. However, for skin-colored, acne-like bumps?often a localized contact irritation?pheniramine alone may not completely clear them. First, please stop using the aloe vera immediately and wash the area gently. While pheniramine can soothe any underlying allergy or itchiness, these bumps should resolve on their own once the irritant is gone. If they persist, a doctor can recommend a topical cream.

Since pheniramine isn't fully helping, you might find better relief with newer, non-drowsy second-generation antihistamines like cetirizine, loratadine, or fexofenadine. For that stubborn nasal congestion and cough, a daily corticosteroid nasal spray, such as fluticasone, is highly effective. You can also use antihistamine eye drops, like ketotifen, for your itchy eyes. Please consult a healthcare professional to tailor the best treatment plan for you.

Dexamethasone (Dexa) and pheniramine (Avil) injections you received in your fifth month are generally safe for short-term use under medical supervision and highly unlikely to harm your baby. For your blocked nose, isotonic nasal sprays and saline drops (like Nasivision saline) are completely safe to use daily. FLORESP (fluticasone) nasal spray has very low absorption into the body and is also considered safe during pregnancy when prescribed by your doctor. If Nasivision contains a decongestant like oxymetazoline, please limit its use to 3-5 days to avoid worsening congestion. Always keep your obstetrician informed about the medications you are using.

Your symptoms suggest that you may have a food allergy. Avoid the trigger foods and consult your doctor or an allergy specialist for proper testing. While Avil tablet (Pheniramine maleate) helps relieve symptoms temporarily, it does not treat the underlying allergy. Your doctor can guide you on long-term management and whether you need an emergency adrenaline pen.
