I have struggled with muscle spasm since I was a teenager. I have steadily increased the dose I take of a muscle relaxant called baclofen throughout the years and I experience a lot more muscle spasm when all I am very tired or I am ill. Like when I had flu about seven years ago – the spasm I experienced then was extreme and left me unable to use my legs at all for many months. I did exactly the one thing I shouldn’t of without knowing it – I rested my body completely. Experience has taught me that the best way to deal with muscle spasm is to exercise especially with gentle movement and lots of repetition. For example my feet would spasm so much in the morning and my PA would struggle to get the splints on my feet that I have worn since foot surgery. So I use my exercise bike in the morning before putting my splints on and this really helps to ease the spasm.

I experience a lot of muscle spasm at night and consequently my legs jump around the bed. To stop this I wear knee immobilisers in bed which works really well. See https://www.healthandcare.co.uk/knee-splints-and-knee-immobilisers.html.
