With SG, our sensory nerves are screaming for input. I have found long sleeves, long pajamas, socks at night, and a weighted blanket helps.
During the day, I find that walking with my four-wheel Walker provides vibrational input through the arms. As I tend to have a heavy and loud heel strike I get both vibration and "joint approximation" input. Initially, I had to wear gloves all the time in addition to gabapentin and pain medication. I have found that by using my hands consistently through the day, even if I spill and drop, it provides the brain some input. The hardest part is mustering up the energy and then patting myself on the back for doing the little things that previously were no brainers. Any activity I do now I consider an opportunity for therapy! Hooray for me.
