De Quervains?

Hi, so I'm a violinist and yesterday my bowing hand (right hand) started tingling just below the base of my thumb. No pain at all, just tingling. Everything I've seen so far points to de Quervains, but the only thing confusing me is that I don't have any pain. I did the Finkelstein test but that only caused mild tingling, and not always mind you. Am I overreacting? Are there any exercises to stop the tingling? It's also happening during the day when I'm not playing, but not all the time. It's really worrying and bugging me, since I cannot let myself not play for weeks, since I'm a full-time music student. I've never had any problems in my 12 years of playing.
