Why is yellow water coming from my right ear?

Your symptoms seem to suggest that you have allergies. Different symptoms including a runny nose, sore throat, and an itchy ear can characterize allergies. Dust, pollen, or keeping pets are the causes of these symptoms. It is important to keep your surroundings clean, use air filters, and take over-the-counter medication for allergies. Stay away from strong scents and consult your doctor for other treatment alternatives.

You might have a medical condition known as "tinnitus". It can be accompanied by ringing in the ears and even the illusion of hearing someone else’s voice echoing. Causes could be exposure to loud noises, ear infections, or even stress. In this regard, you should reduce your exposure to environmental noise, stress-excessively manage your life without resorting to medicines, and use background noise.

Your son has enlarged tonsils, he slows down when sick. These can make the throat hurt, make it hard to swallow, or even block some air. Helping him stay comfortable might include giving him lots of things to drink and soft things to eat. Make a doctor’s appointment if he seems very uncomfortable or it’s hard for him to breathe.

It appears that you have a prolonged sore throat which may be due to hidden factors such as allergies, post-nasal drip, or even acid reflux. Therefore, it is possible to feel discomfort if speaking for a long time. You can reduce the symptoms by keeping your fluid intake high and by using a humidifier in the case of dry environments. Patients should also use Throat lozenges. On the other hand, since this is a recurring issue over many years, I very strongly suggest speaking with a healthcare professional. 

A fever and headache usually tell you that the body is busy throwing away an infection from it, such as a cold virus. Consume plenty of fluids, take rest, and you can also take “over-the-counter” pain relievers such as acetaminophen or ibuprofen to help with a headache and fever. Besides, soaking in a warm shower or using a humidifier will resolve your stuffy nose too. If the symptoms worsen consult a doctor.

The feeling of noises in the ear, called tinnitus, can be very distressing. Tinnitus in such cases is usually nerve damage caused by the mumps infection. Sadly, in some cases, the hearing loss may not be reversible. To manage the symptoms, your brother can try listening to soothing music, using white noise machines, and avoiding loud noises. Counseling or therapy can also be helpful for the patients.
