Thank you for the information.
It would be helpful to see your doctor first just to be sure this is not a physical issue. What you describe could be an inner ear infection or some type of cold or flu bug. It is always good to rule out any physical problem first so you do not end up treating this as an emotional issue and all along you just needed anti biotic medication from the doctor.
I do agree that tapering off your medication without the doctor's supervision is not a good idea. Many medications can have severe side effects and even result in serious health issues if you do not taper them correctly. So you may want to wait until you can talk to your doctor to find out how you should cut back.
All medications can cause odd side effects. Everyone's body is different so how you react to a medicine can vary. And new symptoms can occur, even if you have been on the medication for a while. So your symptoms could be caused by the medicine. It is not a typical response in my experience but it is better to let your doctor rule that out first.
If your symptoms are mental health related, they may indicate that you have some anxiety
symptoms. Odd bodily sensations tend to be common in anxiety, especially pressure and sensations in the head (from tension) and sometimes ears (balance and sounds are not unusual). Stomach upset is very common with anxiety as well. And if you already have depression, anxiety often accompanies it, and vice versa.
If you are in therapy, talk with your therapist about being evaluated for anxiety. If you are not in therapy, consider going to see someone. You need to have an evaluation to see if anxiety is a possibility. Not everyone has all the symptoms of anxiety if they do have it. Some only have a few. So by getting an evaluation you will be able to know whether or not this is an issue for you.
I hope this has helped you,
