I have very poor fine motor skills: my hand writing is terrible, im awkward with my hands and its very frustrating. is there a medical cause for this?

Yes: Your age and medical history are critical to this question. You are describing "tremor" and there are many ways to treat this.Contact your dr.He/she can probably help.

Yes, need specialist: Fine motor skills generally involves proper use of fingers in conjunction with the eyes and the brain. The problem described requires a careful history by a knowledgable physician. For example your age, is it new, is it progressive, is it lifelong, is it a problem developed after head trauma etc. You need a fine neurologist. Allow me to refer you to a 'colleague', dr. Arielle kurzweil.
