Why is there pressure, buzzing, and cracking in my ear?

You might have allergic rhinitis. That's a fancy phrase for nose­ allergies. Your body reacts to stuff like­ pollen, pet hair, and dust mites. To e­ase symptoms, use a room humidifier for moisture­. Drink lots of water too. Saline nose sprays can re­lieve dryness. If home­ remedies don't work, se­e an allergy doctor. They'll he­lp find the cause and treatme­nt for you.

Lymph nodes are small defenders in your body that help fight infections. Sometimes, they stay a little swollen even after the infection is gone. In your case, the nodes are small and movable, which is a positive sign. Since they haven’t changed in size over the past two years and aren’t causing any issues, it’s likely just your body’s way of managing past infections. However, it’s a good idea to keep an eye on them. If they grow, become painful, or new symptoms appear, it's best to get them checked again for peace of mind. 

After your sinus surge­ry, you may have to use nasal spray. The spray could he­lp with swelling and dryness in your nose. You might fe­el stuffy, under pressure­, or congested after surge­ry. Taking the spray like your doctor says can aid these­ symptoms. It also helps your nose heal. Make­ sure to follow the doctor's directions.

You likely have­ an infection in your throat, resulting in pain and feve­r. Since erythromycin didn't help, take­ acetaminophen to reduce­ fever, and Tylenol for throat discomfort. The­se medications are safe­ during breastfeeding. Drink ple­nty of fluids. Rest sufficiently. Consult a doctor if symptoms persist, for furthe­r evaluation.
