I am a 20 year old male. Overall healty. I do not get sick very often, occasional stomach virus, flu and strep throat. 4 years ago this christmas, i was in a car accident and hit my head on the drivers windows. I blacked out momentarily and came to. It seems that maybe 5-6 months later i slowly began noticing small areas on my body in pain. They felt like a pinch. I also noticed muscle tremors, and sometimes my whole body or leg would flinch while laying down or sitting. I also noticed chest pain and pain in my left arm. I also noticed that where my "funny bone" is, theres a small lump and it is very sensitive to touch. It was ruled out as nothing serious. I went to a cardiologist for the chest pain and after an echo they discovered mitral valve prolapse with regurgitation. I feel that my neurological symptoms have been getting worse lately. Tingling in my arms and legs. It is not from sitting awkwardly or cutting off blood. I could be standing or sitting perfectly upright. I also have noticed, sensations, in my forearms and fingers and toes. They are not painful, but it feels like there is a pressure or tightness. I have not noticed any numbness or muscle weakness. All these issues cause trouble sleeping and anxiety. I would just like to know if it's something serious or something I just need to learn to deal with. Help.
