Greetings Alun. Well done for seeing the light.
All I know is, taking muscle relaxants, anti psychotics & anti depressants, didn’t work for me. And that’s where I was channelled, through medical circles. The human body is quite good at self repair, once we know what’s going wrong & feed the required needs.
Exercise is paramount. Be it getting out in the fresh air, or doing some light physical work. Something to get our system functioning. Use it or lose it & socialise with good people. The nervous system is very complex & it needs care.
MS is said to be an infection, where our own body, starts attacking the nerves. The number of people I know who get on my nerves, had multiplied. So I ditched them & all their problems. Look after yourselves folks.
There is no cure for many conditions & the miracle is what we exist in.
Add some useful things to your life & move on.
