TSH level was 24.8 but I'm 18 lbs underweight. Had a baby 7 months ago. I feel terrible-exhausted, irritable, short term memory, swaying feeling, cold, dry skin, hair, etc. can anyone help me understand my levels TSH high but T3 and T4 were in normal range??I haven't started any meds yet. Once I do how long does it take to start feeling a little better? I'm scared, confused, and just feel so off
