severe heart palpitations and i get so weak that like all of a sudden i lose almost complete control over my leg s or arm it feels like a falling type of feeling or how you feel when someone startals you, and then im like jello it is all i can do to make it somewhere to sit down sometimes i get it when i lay down to, feels like im gonna pass out to sometimes, and also i get numb in the face eyebrow legs or wherever - i have been undiagnosed for three years i have the worst doctors in the world - i have spent three years being called a nut and when i finally snuck to the er one night when i had the numbness and told the doc i thought i had mxeyedema coma cause i was hypothyroid and off my meds he did a full panel and my t4 was .063! of course i lied to him but after three years and about 150 doctors visits and getting called and diagnosed as crazy i was desperate not to die! my point with the story is that i am very severely hypo and have been untreated for a long time (just started meds! thanks to myself) so i do not know if someone else would have symptoms as bad as mine or not, if anyone does please share!
