Henk, like you, I have not been to a neurologist yet either. I have some insurance problems and I won't be able to go until the new year starts. So, naturally I have done a lot of web research and reading people's posts to see if their symptoms match mine.
I also came across the symptoms on this site in frequently asked questions that exactly describes what my symptoms are. At this point I am 99% positive that I have BFS based on how this reads below and what I have read on the message boards. I have no muscle weakness, no atrophy, and my twitches travel all over my body. They are primarily in my calves and feet (which is a classic symptom) but on some days and nights they are everywhere, hands, upper arms, thighs, neck, lip, back, etc.!
======================================
Here is what it says:
Common symptoms of BFS are frequent muscle twitches, generalized fatigue, pins and needles sensations, migrating numbness, muscle cramping and/or spasms in the affected areas (my comment: usually the feet and calves but can be anywhere), muscle aches and stiffness, exercise intolerance, headaches, and itchiness.Clinically some patients have mild increases in creatine kinase. Muscle biopsy may show mild neurogenic changes. Electrodiagnostic studies show peripheral nerve hyperexcitability.Often the symptoms will get worse at night, or during periods or sickness or viral infections, stress, or overexertion. (My comment: however, there are days when twitching will occurr all day for no apparent reason.)Many people experiencing these symptoms fear they may have ALS or MS. A simple clinical rule is that fasciculations in relaxed muscle are NEVER (emphasis mine) indicative of motor system disease unless there is an associated weakness, atrophy, or reflex change. ========================================
In other words, if you go to a neurologist and don't perform well on many of the tests PLUS you have a localized twitch in the same muscle where there is CLINICAL weakness or atrophy, then it is possible that you might have something else besides BFS although it certainly does not have to be ALS. When I speak of clinic weakness, I'm not talking about the feeling of fatigue and stiffness that we all get in our muscles because they twitch all of the time. Clinical weakness would be something like not being able to hold a pencil or not being able to pick up a foot to get up the stairs.
From the Yale NeuroMuscular Dept: The median age of onset for ALS is 55-66. The primary symptom of ALS is progressive weakness.
Even though the folks on this board can assure you all day and night that you don't have ALS, you MUST go to a neurologist as soon as possible to get a diagnosis or you will twitch more and more just due to the stress of worrying about it! Make the appointment right away for your own sanity!
Hopefully you and I both will get a benign diagnosis! The more you worry and stress over this, the more you are going to twitch. If you think about a muscle long enough, wondering if it feels odd, it WILL start twitching and it definitely WILL begin to feel odd or sore or stiff or tingly (I know because I do it myself). I've noticed that if I watch a funny movie or play with my kids it mysteriously goes away
We can do a lot with our minds, including focusing all our attention on what we DON'T WANT to happen, which will likely bring on a lot of physical distress in addition to the mental and emotional pain. Focus on what you DO want to happen which is to be healthy and strong. I don't mean to sound trite, but try to do something that makes you laugh, be around healthy people (even if they are little kids) and laugh with them, exercise enough to clear your mind, and stay positive. That is better medicine than a tranquilizer or anti-depressant pill and will go a long way towards calming your muscles and your mind. By the way, this is advice I give myself, too, because I do the same thing you are doing. It's very easy to start combing all of the message boards trying to find reassurance and then end up in bad shape because you read what someone else has written. Take a break from reading the boards and hanging out where you do nothing but read medical symptoms. You've heard of medical students who think they are dying from every disease they learn about, haven't you? If you study it, focus on it, you will begin to feel and experience it. Not the real disease, but the symptoms of the disease.
I am my own worst enemy quite often.
Cheers!
