Well I should know better really, shouldn't I?! I have travelled the rocky BFS road for 13 months now and have yet to develop much that would point to MND/ ALS! I have been told three times by my neurologist that she is 99% sure I don't have this dreaded condition (despite the odd brisk reflex on examination here and there, the odd scary terminology of 'denervation/ renervation' in one EMG report and some recently discovered quads asymmetry corresponding to the EMG findings - I trust that the neurologist's reassurance that this is probably just a slipped disc is accurate!) I have watched my calves and feet twitch day in day out for over a year and still I can walk a mile up the steep track near my work. I now ignore these twitches.So why oh why I am I so spooked by my L thumb twitch? I have gone to YouTube and typed in 'thumb twitch' and watched a couple of people's recordings of their thumbs twitching - mine looks no different. I have typed in 'thumb' in the search function on this site and found 141 pages of posts about thumbs, many of which recount reassuring anecdotes which sound similar to my own experiences.Despite all of the above, whenever I see my L thumb twitch I start feeling sure that this is the beginning of the end. So it would be really good if anyone who is currently active on the site and who has symptoms similar to my own (see below) could make themselves known and help reassure me!6 week history of daily twitch in L (non dominant) thenar muslce - between the palm and the thumb, present for about 50% of the waking day and occasionally forceful enough to wake me from sleep. Often associated with a visible but small movement/ flick of the thumb. Associated with some crampy pain from time to time. I can't work out why I should be so wound up about this particular symptom - maybe because it is new, because it hasn't settled down like other 'hotspots' have in the past, maybe because it is so difficult to ignore, being in my line of vision all the time... not sure. Anyway, any support would be grateully received.Thanks in advanceKind regardsSimon
