Hi there. I'm not called Paul, but everything you say is the same for me, except it seems it is just my left calf that goes off non-stop when I'm at rest, not to mention the weird vibrations that I get in that foot as well. I also get twitches all over on a less regular basis, at least a few every hour, especially the other calf, shoulders, thighs and hands and feet. I was having these less regular twitches all over for many years until about 2 months ago when my left lower leg started to do the full-on thing that it now does 24/7. I have to say this change in symptoms, especially with some cramping that I was also having, was particularly disturbing for me as I thought this was progression. However, it remains unchanged as I write this. I have no weakness or loss of muscle mass and believe me I have been examined and tested!I should add that I am also a physician and have previously worked in neurology at a top teaching hospital in London and seen many patients with neurological conditions. If I was my own patient, I would be giving reassurance and advising relaxation and anxiety management. But this is me and my symptoms are very real and even though I can talk myself through my symptoms and why it is likely to be BFS rather than anything else, it doesn't stop blind panics and the irrational thoughts I have -especially at night. Anyway, I fully empathise with all that you are saying. I really understand why it feels like it has to be something serious because it just seems so darn abnormal. All the advice I have been given from medical colleagues of many years standing points in one direction, and that is, in the absence of other lower motor neurone symptoms (i.e. weakness and muscle wasting), then fasciculations alone are not clinically significant and are very common in healthy people, but they just happen to be far more common and prevalent in us sufferers. I hope this helps. It is enormously useful to read the details of others' experiences, especially the finer details of their symptoms, if only to realise that we are not alone and through this there is some reassurance.
