Are Cramp Fasciculation Syndrome & Radial Tunnel Syndrome related?

I was diagnosed with Cramp Fasciculation Syndrome (CFS) about forty years ago and after trialling numerous prescibed medications, nothing worked and only caused depression. So I've just given up and deal with the cramps and twitching. Originally, the cramps & twitching were restricted to my feet, calves and hand, getting several cramps a day. Now, I experience several cramps an hour in numerous muscle groups throughout the body, including occasional abdominal & diaphram muscle groups requiring to be rushed to hospital to assist with breathing. Over the years, I just learnt to 'suck it up and deal with it'.
Recently, I've developed Radial Tunnel Syndrome and I'm now wondering if this could be related or caused by CFS or something totally different. Any clues or advice?
(P.S. I'm 70 years old.)
