Hi Yanks, sorry to hear about your popping of the ears/tinnitus after your weight lifting. Hopefully this message finds you in time!
I recommend yoga as a supplementary treatment to both hearing loss and tinnitus, as yoga helps to increase blood flow to the ears, and relax muscle tissue. As a side-benefit it also releases feel-good hormones, which it sounds like you're needing.
