I have been using an FES for over six years without any problem whatsoever. Suddenly my skin is reacting to the electrodes and is developing little tiny pimply spots and a red rash. This happens when the FES is sending power to the electrodes. It is very painful to use the FES so I have now put it away and must use a Musmate.
I really want to know if anyone has had problems like the one I have described.
The consequence of this is that walking is now all but impossible, I have an EDSS of about 6.5 and the FES makes a huge difference.
