Finger tremor
by Aeroguy, Aug 15, 2003 12:00AM
I'm a couple of months short of my 29th birthday. For the last few months, my left pinky finger has begun to twitch. It seems to twitch at a constant frequency of about 2 Hz and the amplitude of the twitching seems to have decreased recently. There are some days when this twitch occurs rarely, and others where it occurs often. It happens sometimes at rest, but usually seems to be triggered when I type or use my pinky in some way. On rare occasions, I feel a very slight temporary tingling in the fingers of my left hand and a slight tightness in my left bicep. Years ago I injured myself and severed a nerve ending in my left hand just below my pinky. For years I had no feeling on that scar just below my pinky. Now the tremor seems to come from the same part of my hand. I have a routine check-up with my doctor in three weeks at which time I will bring this up. There are no cases of Parkinson's disease in my family history. I read on a another web site that tremors can occur due to prolonged periods of high stress, which I unfortunately underwent at work over the last year and a half. What is your opinion of my situation?

Abnormal movements of a particular body part can be do to tremor, muscles twitches, or abnormal postures secondary to dystonia. You state that these movements occur usually with action, and therefore they may represent an action tremor. Stress and stimulants, such as caffeine, can exacerbate these conditions. Irritated muscles can sometimes cause intermittent twitches, so if you have been doing more typing then usual that also may be a possibility. Lastly activities which are repetitive could cause a dystonia. This is a disorder in which a person wants to do a particular motion, but incorrect muscles get activated by mistake. I think discussing this with your primary doctor is a good start, and then consultation with a neurologist can be performed as needed. Good luck

Oromandibular Dystonia. Abnormal movements involving jaw and tongue which severely affect my speech and eating. I took Seroxat 5 years ago for 12 months and have been taking infrequent doses of Zopiclone for 2 years.
I also take Tamoxifen for breast cancer and Thyroxine for underactive thyroid. Are any of these medications responsible for the Dystonia?
