I knackered a tendon that run from my finger all the way to my elbow on dec28th
I knew it was a bad one and stopped climbing. I climbed for an hour on relatively easy routes 2 weeks ago and it throbbed for 2 days after. I am only now thinking off trying again 9 weeks after the initial injury.
The trouble with tendon injuries is that they take ages to heal and if you climb on them before ey are ready it makes them exponentially worse.
The four letter word climbers fear so much
REST. And lots of it I would say if you want to make sure you don't do any lasting team age I wouldn't think of climbing for a couple more months.
As far as treatments go other than resting, icing definitely works
