[Luisa Sutherland]

When I was 12, I started getting tingly patches in my skin, nothing to see but it was sore and came and went for no apparent reason. GP didn’t investigate it. When I was 16, my mother was diagnosed with MS, and I realised that that was probably what was wrong with me too. But I wasn’t taken seriously until I was 28 and went blind in one eye (optic neuritis, which has been a common symptom, in varying degrees of severity since).
