could this be a tumor

My husband is 33 and last week developed a serve hand tremor on his left side and just a little on his right (the right side hardly ever tremors).  He went to the doctors and they said to come back in 10 days if it had not got any better.  They said it might be something he just has to live with.  They also gave him a beta blocker and said it should help.  After seven days the tremor is no better and on his way home from the doctors the tremor got really bad in both hands and he rolled the car.  Thank goodness he was fine.

The tremor is mostly a resting one and also against gravity.  And at times seems to be getting worse not better. Things that we have noticed, that might not or could be related are, that he has bruising easily (especially under the upper arms) and we found a nickel size lump on his upper left arm (we don't know if it is from the none stop tremors and there being a muscle knot).  His thyroid was tested 4 weeks ago and it was normal.  He has been having difficulty with concentration and been eating like crazy. He is very healthy with low body fat and great blood pressure.  When he draws things like spirals they have little notches very close together.  He does not having any problem moving anywhere else in his body.

The doctors we have seen don't seem very concerned but do you think I should push them to recommend him to a neurologist or someone else. Could it be just essential tremors?  Or is it more serious like a tumor.  Any info would be great.  Thanks for your time in reading this.

Well, Hopes;

   Hubby is pretty young for Drs. to toss a beta blocker his way and say, "You may have to live with this" and have little concern.
   If they don't refer to a neurologist, I would make appt. with one on your own.

My husband tremors are still none stop expect at night and this is going to sound odd but he has uncontrollable laughter at moments. He does not know why he is laughing.  I have never seen him laugh like that before. We are a waiting list to see the neurologist.
