Hi ! From the history it seems necessary to rule out hypothyroidism
in your case. The symptoms you have narrated including the fatigue
, Raynaud's phenomenon and weight gain can occur in Hypothyroidism.You can consult your doctor to rule this out.
Your spells of freeze and fall may be an independent entity and could be related to the partially blocked carotid artery
as of last year, which might have increased by now, and might be responsible for such attacks, known as Transient Ischaemic Attacks ( TIA ). You better get it checked again, and consult a vascular specialist dealing with such pathology at your place. Your family physician may be able to guide you on this.
Wishing you an early recovery. Thanks.
