Muscle tears take 6 to 8 weeks to heal completely; tendons somewhat longer depending on a lot of things, like whether it was a partial tear or a catastrophic one. If it was catastrophic, you'd know it right away, so I'd say partial (of course I'm not a physician it goes without saying). Like Alex says above, personally I'd counsel caution and taking my time. I did partially tear my supraspinatus tendon once and it took a heck of long time to completely heal. Ever heard about using those little 3-pound weights and a theraband to strengthen the muscles around those shoulder tendons? Sure someone can show them to you. In the meanwhile, take it easy. Don't want to go tearing those tendons through all the way. Then they're kaput unless a surgeon's knife puts them back together. If it's any consolation, I know tons of people who've healed back up from tendon tears without visiting the surgeon. I know how frustrating it is once you have developed a bouldering routine to pull back, but it's a lot better to err on the side of caution. Tendons are very low on oxygen to begin with so I'd guess that TMS could interfere with the healing process too. You could also check yourself out with a full range of motion studies with your arms at various positions. If you can hold your arm out straight in front and above you, the tendon probably isn't completely torn through. Like the docs say, "an MRI doesn't lie", but a range of motion study can tell you a heck of a lot too. When in doubt, have a doc check it out.
PS- What you describe does not sound like a catastrophic tendon tear to me. Having done that, I can say with absolute certainty that you'd really notice it. Tendon tears hurt like crazy. Tons of kids around my climbing gym who have to quit campus boards for a month or more. Kids are crazy: they'll work on campusing 5 hours a day and wonder why they hurt. The problem as it has been described to me is that muscle strength improves much more rapidly than tendon strength. Time is the great healer and patience is a virtue.
