Hi, This is my first post to this forum. To briefly introduce myself, i am a 24 year old Norwegian male that started with the twitching(at least that i noticed) during October last year. I'll start from the beginning: Sometime during last fall i noticed that my hands were trembling. I didn't really think much of it as I had just moved and started working, thinking that it was due to change in eating habits and less sleep. I looked up trembling, twitching etc at the Internet although I didn't twitch at the time. The trembling continued, and I later noticed that not only my hands, but seemingly the entire body seemed to be trembling somewhat. Then the twitching began. I noticed it first in my left arm and just below my left eye, not really giving it much thought as i went over quickly and didn't return for some days. Then i started getting twitches all over, although far more on my left side than the right. Googling began, and the fear of ALS took over, as seems to be the case for many here. I began getting some really aggressive left shoulder/back twitches, and called the doctor, getting a neurologist appointment about a month after the twitching started. The neurologist did some strength tests, reflexes etc and said that he was certain that i was perfectly healthy, and that the twitching probably had started due to me being previously very active, with heavy workouts 5 days a week and then abruptly stopping some months previously due to masters thesis and summer vacation. I asked about an EMG just to be sure, but he stated that this wasn't necessary as it would only prove what he had already said. He seemed very certain, and for the next few days I twitched far less than I had previously. Then it flared up again. About a week ago, i started becoming really concerned. I noticed what seems like a smaller muscle between left thumb/index than my right. Another thing i noticed is that if i stretch my thumb to the side, there is a larger hole between the two tendons(?, don't know the word for these in english) at the base of my thumb of my left hand than my right. Should i be concerned about this being atrophy? Additionally, my left foot has been acting weird. Somewhat tickling sensations, sometimes pain, cramps more easier than before and the balance seems to be worse standing on my left foot than on my right. If i stretch out my toes on both feet, the tendon in the arch at the left foot is far more visible than in the right. The outside of the foot also seems to be less muscular on the left side. Atrophy?Today i decided to test my finger strength, leading to this post. Keeping my fingers extended it was far easier to push down my left thumb than my right. I then tried lifting a bag with a book in it with my thumb, thumb extended. I could barely do this without my left thumb "falling" downwards. With my right thumb, it was no problem. Of course, it might be natural that my less dominant hand and its fingers are weaker, but I am afraid this might be due to the possible thumb atrophy mentioned above, i.e. due to early als. I am quite concerned now, even though i am aware that the chance of this actually being ALS is low. The twitching is mostly in my left arm/shoulder/back. My thumb/left arm might be atrophied, and my left thumb is weaker than my right, i.e., seemingly onesided problems. I hope someone can post some encouraging words, or of similar experiences turning out to be this benign phenomenon. Sorry for this long post.
