When should I tape a finger pulley injury (ie A2 pulley), and can I still climb while it is healing?
Get a proper diagnosis first and the right treatment. Generally a fresh single pulley rupture (normally A2) does not require surgical repair, only multiple pulley ruptures do. A single pulley injury can be healed by taping it functionally or by wearing a softcast ring. There should be no climbing between 6-8 weeks, depending on the symptoms. Other finger injuries may require splinting, taping, ice baths, a local injection of corticosteriods, painkillers, or simply just climbing less intensively using more open-handed holds. Definitely get a proper diagnosis by a skilled doctor with expertise in this area.
