Hi my son is 5 his problems started at 4 months old suffering non epileptic episodes of shaking. As he got older this led to episodes of wobbly walking, complaining of legs feeling funny, regression in speech, some behavioural issues as a toddler. Currently he suffers a lot of fatigue which is getting worse, constantly complaining of legs in feet and or legs/hands/wrists/fingers and often feeling sick. His mood switches very quickly and often results in tears. In Jan his tsh came back at 4.37 (range up to 4.2) so I requested b12 etc tests, his neurologist tells me everything is normal, I'm not convinced, any advice?
