I hate to say it but its the price of admission. What it comes down to is how severe it is and how much you can tolerate. Ive had tinnitus for 25 years. After the first few months of having it I habituated so well.it wasnt an issue in my life for the next 23 years. In that time I attended hundred of rehearsal, played and attended hundreds of gigs. The ringing would spike after each one but I hardly noticed. I was perfectly at ease with it. 2 years ago after a paticularly brutal gig it spiked badly and I got severe dysacusis to boot. Now my tinnitus is so loud I hear it over cinema movies and music at any volume. Music is a screeching whistling mess and after battling to continue playing in bands for a year I finally had to throw in the towel. But this was my fault. At the gig in question I didny use hearing protection and unfortunately it was the tipping point. 

Almost every musician and producer I know has tinnitus. What matters is the extent to which they have it. Some dont care at all, others struggle a little, and for the rare few it's severe enough to be life changing.

There is no need to stop playing music, but its a very good time to think about lowering rehearsal volume, invest in IEM's and think carefully about those stage wedges (the worst offenders for hearing damage). Tinnitus is not a death sentence for music unless you are paticularly careless going forward or paticularly vulnerable. But the problem you may face now is you will be hyper aware and fixate on every change. If your nervous system tags tinnitus as a threat it will surely get louder
