3-4 months was my experience without serious drugs as was just an overuse/poor training in past thing
this time included building some strength so could start climbing again without damaging again
Physio though i was doing pretty well in early stages and quizzed me on what i was doing and seemed a bit shocked when i said was actually doing the stretching exercises 4 times a day
– found riding MTB made me sore – combination of the shaking and/or hitting the ground! but road should be ok if training for a Tri – running a bit of discomfort but stretching afterwards under the influence of ibuprofen seemed to work without retarding recovery
lots of self help stuff on climbing sites as a pretty common injury
good luck – i felt in early stages that i wasn’t going to recover but it did come with effort at least with the severity i had
