I was doing CBT. I saw a therapist for 2 sessions. She was telling me to get back to my life. I was avoiding lots of things before so I started to try and be more normal. I went to a bar once, not too loud, didn't wear earplugs though, had some slight pain the next day but nothing serious.
I started playing music a bit louder on my speakers while I was lifting weights at home. Sometimes re-racking the weights was loud. I was driving my car, with a loud exhaust, without earplugs. I was exposed to my dog barking several times which was very loud. Fire alarm went off when I wasn't wearing hearing protection too.
I don't know what caused it exactly but I went back to square one again after being much better for a while. I had massive pain again for almost 2 months.
The pain is much better now though, but I still have slight aches.
I was getting some warning signals last time with pain where I should have protected my hearing more but I didn't. Now I will just protect my hearing more when I think I should. If I manage to avoid the things that triggered me before I will probably be fine.
