Ruptured/repaired mine in 2001.
I don't remember exactly, but I seem to recall it was ~2 months.
Let's see--what time is it now? Seriously though, ever since the rupture, a small part of my awareness is always 'on guard,' monitoring the status of my tendons while I'm lifting.
As an aside: I worry more about the other tendon than I do about the repaired one.
Never. (Although I should add that I changed my style of lifting after the injury--higher reps, lower weights.)
I would add that there is a bright side to a distal biceps rupture. In repairing it, the surgery lengthens the muscle by ~1/2 inch, give or take. As you know, longer muscles look fuller than do shorter muscles. As a result, my s/p repair biceps actually looks better than the other one.
If I may offer some unsolicited advice: Be circumspect with the pharmaceuticals--some have the potential to make the situation worse.
Finally, what does skinning the cat mean?
