This is a area of interest for me too. I've only recently become aware of aching (muscle wasting ?) in my thigh area and am naturally anxious about it spreading or worsening.

I suppose I could get referred to an OT and perhaps I should. I don't swim, but do a reasonable amount of walking, mile a day average, up to 3-4 weekends. I haven't cycled for a long time but am pondering trying this or even an exercise bike, but don't want to do more harm than good !

Has anyone got any experience or advice they can share please ?

My PN is diagnosed as alcohol related - I've stopped completely - so hope things won't get worse.
