Living with Essential Tremor

Hi, My name is Zamil and I am 48 years old. At the age of 34, I felt that I have tremor on my hand. I went to doctor and the doctor suspected of having essental tremor as my brother and my mother have the same problem. The doctor gave two medications, one to control tremor and the other was Relaxing. My tremor did not stopped but it was controlled to some extend. About 6 months ago, I started having tremor on my hands as well as on my legs. So, I went to another doctor (neurologist-medicine) who gave me two medications in addition addition to the one that I had been taking and withdrew the relaxing. It was controlled better then before, as the frequency was much less. But since last week, I started feeling uncomfotable with my legs, seems that my legs are very tired, bones having light pain 3 to 5 times a day, stays about 5 to 10 minutes each time. I went to another neurologist yesterday with the complain of having tired legs and pain, and he kept the same medicines with higher dose. Some one please advise me if it is OK, as I was suspecting that the tired legs and pain in the bones could be the side affect of one of these medicin.
