Hi JLH,
Although it reads on your profile cause of tinnitus unknown, in most cases something is responsible for it. The most common cause is exposure to loud sounds. Typically, it is listening to audio through headphones, earbuds, headsets, AirPods, noise cancelling or bone conduction headphones without realising it. Other types of exposure to loud noise can cause it too.
For the moment I will assume your tinnitus is noise induced and therefore, it's not a good idea to be isolating yourself from normal everyday sounds, as this can result in the auditory system becoming more sensitive as you have found.
Tinnitus can cause a lot of stress and anxiety in the early stages and this needs to be managed, otherwise coping with it can be difficult. Stress makes tinnitus worse and tinnitus makes stress worse so it can become a vicious cycle. Some people try to push through this, preferring not to take medication but usually this isn't a good idea, because tinnitus is an integral part of our mental and emotional wellbeing and is quite capable of wearing down a person's resolve. St John's Wort is used to help control mild to moderate stress and takes time to work. Prescription antidepressant usually act quicker and are more effective at controlling a person's moods so they don't become too down by tinnitus and hyperacusis.
You are quite right, medication won't stop tinnitus but it can help to control it by acting as a safety net so you don't become too down. The less stressed a person is will have a positive impact on the tinnitus, by making one's perception of the noise less.
