For awhile now i have had very strange symptoms. It all started when i hit my head and had bad whiplash and got a concussion. 4 years later i still have bad migraines my legs tremble uncontrollably when i bend to do things like changing my tire and even walking down the stairs at times. if i hold a glass or my phone my hand starts to tremble after awhile. I feel like my cognitive ability is declining. I have had so many blood tests and xrays, colonoscopy's done and everything has come back normal. Im scared its something like ALS or cancer because im so tired all the time. my voice gets hoarse mid way through the day. I have pins and needles at times too. There are a lot of symptoms like feeling tired after eating sugar but i haven't found anything wrong yet.
