I wonder if months of doing eccentric curls and no real pull up type stuff (concentric) was counter productive or worse?
pure eccentrics are somewhat discredited by the most recent research into tendonopathy rehabilitation in favour of concentric/ eccentric regimes, which your experience appears to support.

First of all.... you injure your biceps and so do lots of exercises on.....your biceps. go figure! Unless it's a cut-and-dry case of tendonitis of the elbow (golfers or tennis, which are both easy to self-diagnose IMHO) then you are best off going to see a doctor or physio who can work out what is wrong. That said I have no idea what TobyD is on about.......literally all the research I have seen on tendonosis conditions since I started looking into it have all supported the idea that eccentric exercises are the best thing ever. Dave Mac talks about them in his injury book, Eric Hurst in one of his, plus the tyler twist style studies and associated anecdotes. Then there is the body of evidence for eccentric exercises for achilles tendonopathy.
If you have say elbow tendonosis, you do exercises which involve your elbow.
Andya few questions about your original post1. what kind of lock offs are you doing, and why? I remember Eva Lopez looking at lock offs in a three part series and concluding, after many caveats, that they are a waste of time at every level?2. eccentrics are recommended for elbow problems but you seem to have a bicep problem. What did the physio/doc say?3. what eccentrics were you doing? There is no concentric move for a lock off, it's static, so how can there be an eccentric move?
It is clear appropriate mechanical loading (not too much or too little) is good for tendons. The jury is still out on whether the load needs to be eccentric, concentric or both, particularly for climbers. ... As usual, rehab. needs to be specific to the activity. If campussing or dynoing gives you problems, then heavy, fast, short-duration, eccentric work might be appropriate. If deep locks are the issue, look elsewhere. Shoulder stability for example.
I was always puzzled as to why eccentric exercises were suggested as being good for tendons. How can a tendon know if its muscle is working eccentrically or concentrically? The golgi tendon organ is stimulated when the muscle generates force, it cannot differentiate between concentric and eccentric contractions. Experimentally, it is not clear that eccentric is better than concentric exercise for tendonopathy. Clinical trials comparing the two protocols are few, underpowered and generally of moderate or low quality (e.g. Larsson et al 2012, Kingma 2007, Woodley et al 2007).
"How can a tendon know if its muscle is working eccentrically or concentrically? The golgi tendon organ is stimulated when the muscle generates force, it cannot differentiate between concentric and eccentric contractions."How do you know it can't?
