HELP

I am losing my mind:

I have had attached fixators since 23rd June and have been working with a computer created plan by which to straighten my right leg at first.

But one of the struts is the cause of constant problems, changing the numbers without any human intervention. This has now required me to return on 3 occasions to correct which is achieved by changing the strut and realignment, the last time was on Friday and everything was thoroughly checked before I left to return home.

Then on Saturday morning rather than reading 76 (gradual), it was reading 69?

Has anyone any idea what may be going on?

I just cannot be spending all this time, let alone the cost which cannot be ignored, to be going to hospital to resolve.
