Its maybe just a coincidence?? I have a tone in my right ear louder than before, vigorous teeth brushing and too much neck movements when hair brushing but then again it could be just doing its own thing. Drink lots of water though to flush your system? Diaphram breath and try to relax even though I know that can be impossible given the circumstances <3

Sorry to hear you are also struggling:-( Thank you for your kind advice 
What does the new tone sound like? Doing research online it seems gut issues correlate with tinnitus cause our gut is connected to what's called the vague nerve. I would say this new tone is probably not permanent and your body is healing from a virus. Give it 2-3weeks to recover
As @Strawberryblonde recommended I would try flushing your system. Eat food high in fiber and plenty of water
@Sammy0225 Thanks so much for your comforting words and great tips ❤️ Will definitely do that!
