Hello I am at 37 year old male. Since late 2005 I have noticed that my hands, back, neck, and legs tends to shake at times when doing certain movements. It is not something that is noticeable by others, but I can feel the internal vibration. I talked to my doctor about it in November. He said it was related to stress and conditioning. I have been a long distance cyclist for 20 years so my lower body has always been strong and I may have neglected upper body works outs. So I hit the gym and my strength is there, but the unsmooth notchy muscle movements and vibrations are still there. The majority of the more noticeable shakes tend to originate from my upper back and shoulder area. If I lay in bed on my back there are no issues, but if I lay on my stomach with my head turned I will feel and hear vibrations in my ears. I can bench press some substantial weight and hold it in the up position with minimal shaking, but if I extend my arms straight out with a 10 lb dumbbell in each hand and hold my arms stationary my back, shoulders and arms start to shake. I am really scratching my head as to what is wrong with me. I run 4 miles every other day, cycle, hit the gym etc. When my body is in motion everything seems fine. When my muscles are not in use everything seems fine, but when my muscles are in use in more of a stationary manner, holding arms out, turning head far to the side, sitting with my elbows on my knees, close one eye and keep the other open the closed eye side muscles can be seen shaking in my face, lifting a wheel on to lugs nuts etc. I start to shake? I just feel like something is out of wack in my system. I can have a bunch of energy then go to feeling tired very quickly. On a positive not my legs seem to be less shaky since cross training between running and cycling. I have research a bunch of conditions and can’t seem to put a finger on anything.
I am going to the Doctor again soon.
