Update:
I saw a family doctor today. He has referred me to a neurology clinic.
I discussed with the doctor my symptoms and concerns. He asked if I had trouble swallowing, or speaking. I told him no. I told the doctor about my twitches in my legs, and my shaking hand fingers. The doctor also, I believe, checked my knees for hyperreflexia; my general walk; and my blood pressure. All were good I think.
I intend on getting a better diagnoses at the neurology clinic, but I am unsure when that appointment will come, usually it takes a while here. I am really concerned abut the muscle cramps in my body (occurring in my calves, thighs, arms, shoulder, etc), and the twitching in my hands (particularly my right), I am frequently making typos while typing/texting, and missing notes while playing the piano. The ring finger, and the pinky finger in my right hand are frequently, but very slightly, trembling side-to-side when I hold my palm up. My pink shakes violently ever- time I tilt my hand at a angle, as shown in the video below, this happens almost every-time:

A quick self test (from my research) of the interossei hand muscles, I notice both my pinkies, but especially my right pink is weak. It can easily be pushed in (4 fingers are spread upon), and it is not resisting to force. Other members in my family have stronger pinkies. I also notice this when holding my smartphone, my right pinky feel sore fast. And raising any leg up (standing on 1 leg), the leg that is up starts burning and feeling sore pretty fast.
