My brother has recently over the last few months (~6) developed tremor.
He said he feels it all over his body, ususally after exercise or standing for a long time. He also exhibits it when making a tight fist or holding a fork, pouring liquid, etc. He said that it is bilateral and is not resting--that is, it is not present when he is at rest. The fingertip to nose and heel to shin tests are no problem for him, and during the former, he doesn't exhibit any strengthening or worsening of the tremor.
He does drink alcohol, perhaps more than moderately, 8 pints of beer maybe 3-4 times a week. He said that alcohol alleviates the tremor. Conversely, he said that smoking marijuana exacerbates it.
He is 38, overweight (6'1", ~250lbs), has SVT and takes 50mgs of atenolol per day. Of note, he said the tremor began after his last SVT attack that required a trip to ER and a corresponding increase in his atenolol prescription from 25 to 50 mgs. I have seen that beta blockers are prescribed for tremor, so this seems a bit odd.
Based on what I have read, it doesn't seem like it would be a Parkonsonian symptom. My question is would MS or cerebellar tremor be possible here? Or more likely just an essential tremor or a more minor problem.
Any insight would be helpful and appreciated. Thank you.
