Mine spikes after the shower, driving, doing laundry, dishes, watching TV, eating certain foods, wearing ear protection, lack of sleep, stress, BP going up,... It always goes back down to baseline so I don't care about the process anymore. My tinnitus can be quite loud but it rarely bothers me and I don't listen for it. My bigger problem is ear pain after sound exposure. Sometimes that can be quite painful. Tinnitus pales by comparison.
