So in January of 2016 I got a concussion when a trunk door slammed my head. Since then I've been battling with dizziness, very poor memory, problems thinking, headaches, all those post concussion symptoms. I'm 18 years old, about 1-2 months ago or so I started getting a stiff type of pain in the middle finger- ring finger section of both my hands and in my toes as well. My palms would kind of get a cramp like feeling as well. Then about a week ago, I noticed that my right middle finger started to kind of twitch. It wasn't happening all day but it would randomly twitch. It's still happening, and then my right toes started to kind of have a weird spasm like twitch. The spasm like twitches are now also happening to my left foot. The foot twitches now basically happen all day. My hands and feet both kind of feel stiff, especially my right middle finger. I'm extremely nervous on what could be wrong, I'm nervous that I may be getting Parkinsons but I'm 18 and it's very uncommon to get something like that at this age. I've had neck pain for many months and I would crack my neck so I don't know if it's tied to that or not. Does anyone have any idea what may be wrong with me?
