With increasing regularity, my hands are suddenly going into a spasm. I can't move the affected hand at the time, and it feels almost locked in place. It's painful and I find the sensation quite distressing. Fortunately, it passes quite quickly - maybe 15-20 seconds.
I'm also really tired and forgetful lately and probably a bit more tetchy than usual too.
Should I see a doctor or is there something I can do at home?
