Hi, I do not know whether this requires medical or not but I guess it worth a try. The thing is that my hand shakes or as I’ve research known as tremor especially the right one. I believe it started around the age of 16 or 17. In the beginning I didn’t think that I should be concerned with it. However, the tremor continues until now. I am now 18 going 19 this month. It doesn’t affect my writing, drawing but it shake when i rest my hand. It doesn’t when i sleep. However when i rely on my right hand to carry stuff such as holding the phone on one hand (right), my right hand shakes. It got a bit visible these days that my friends and family noticed it. Could it be due to coffee?When it comes to coffee, my dose is quite high ( ristretto bianco) and i had start drinking coffee at the age of 15. What do you think about it?
