I'm having some issues with my hands; there's this strange tingling or jhanjhanahat that I can't shake off. It feels like my immunity isn't up to par lately, and I'm also feeling really cold all the time. Can you help me understand what's going on?

Postnasal drip or nasal discharge can be a concern. Possible causes: 1. _Allergies_: Seasonal or environmental allergies can trigger excess mucus production. 2. _Sinusitis_: Inflammation or infection of the sinuses can cause nasal discharge. 3. _Anatomical issues_: Deviated septum, nasal polyps, or other structural problems can contribute to nasal discharge. 4. _Infections_: Cold, flu, or other respiratory infections can cause nasal discharge. To address the issue: 1. _Consult an ENT specialist_: Rule out underlying conditions that may require medical attention. 2. _Use saline nasal sprays_: Help moisturize the nasal passages and thin out mucus. 3. _Try steam inhalation_: Ease congestion and promote mucus clearance. 4. _Maintain good hygiene_: Regularly clean your nose and surroundings to prevent infection. Monitor your symptoms and seek medical attention if: 1. _Discharge is yellow or green_: May indicate infection. 2. _Discharge is bloody_: Requires immediate medical attention. 3. _Symptoms worsen or persist_: Consult your doctor for further guidance.
