Struggling with Normal Thyroid Levels but Feeling Terrible

There is a difference between being within "clinically normal" and "optimal range" for your age/other health factors. Being within your optimal range can be the very thing that determines the severity of your symptoms even when you're clinically "normal". I try to get my thyroid levels checked every month... In January my TSH was 0.7 (close to hyperthyroid). In March, my TSH was 2.3, which I felt was high (hypothyroid). The thing that makes Hashimoto's different between other Thyroid issues, is that you constantly swing back and forth between hyper and hypo. It's a specific condition! The constant swing between the extremes and then the constant swivel between normal, but not optimal levels is enough to put your body systems through the ringer... Hence the fatigue, brain fog, and body pain. I always wonder WHY, when my levels change so much so often, WHY is my Levothyroxine dose not adjusted to keep me at my optimal level. Doctors and medical professionals do not talk enough about optimization for individualized health. I only had one doctor talk to me about this, and he was a fill in until the office found another endocrinologist. The journey is maddening
