For about 3 months I noticed problems with balance and some

Thank you for the additional information.

I ask these question for a couple reason. Although the symptoms that you describe are extremely more likely due to ear disease, when someone says that they feel like they are going to faint, it raises a question of whether the blood pressure is getting too low at times. With the blood pressures that you describe, this would be less likely, but ideally, it would be good to check the blood pressure when the person is feeling faint.

Regarding the ears, the fullness in the ears is most often seen from chronic inflammation in the ear, most often from allergies, although there are other possible causes, such as vasomotor rhinitis. The symptoms are also suggestive of Eustachian tube dysfunction, which also can be related to chronic inflammation and allergies.

Chronic dizziness can also be due to a couple of other common problems, including BPPV, which is due to crystals forming in the inner ear, and Meniere’s disease, which is due to fluid accumulation in the inner ear. Head exercises are usually done to try to help with BPPV, while diuretics are usually used for treatment of Meniere’s disease. One of the reasons that I asked what medicines you are taking is that many people are taking a diuretic for other reasons, including one of the components of the Co-tenidone.

There are several interventions that can be done at this point. The betahistine is one of the usual first-line medicines used to help with dizziness due to ear disease. There are some other similar medicines that are available over the counter, such as meclizine. These other medicines work similarly to the betahistine; it is not that one is better than the other overall, but different people may find that one drug works better than another for them.

It also may help to perform different Eustachian tube exercises. You have been trying one type of exercise by blowing while holding the nose. There are some other exercises that can be tried, including forced yawning, chewing on gum, blowing up a balloon, or drinking fluids through a straw, preferably a narrow straw or a thicker liquid (or both).

Other interventions would be to use a nasal spray of steroids, which is available over the counter in some countries, but requires a prescription in many countries. It may help to irrigate the nose and sinuses with warm salt water, such as with a NetiPot.

If I can provide any further information, please let me know.
