In reply to K Farrell:
Yup, know all of the staff there and any one of them would be able to help with the sort of issue you’re describing. They won’t just keep taking your money either. They’ll assess, diagnose, and agree a plan with you at the offset.
Running specialist there is Lee Shimwell, who’s a good standard fell runner. But this sort of issue is likely to be bread and butter for any of the gang there.
Good luck, hope you get sorted.
