Hi. I've been hypo for 18 months and been on levothyroxine for all of that time. My last TSH was 3.97 on 100mcg daily but was experiencing severe joint and muscular pain since I was increased to 50mcg daily over 6 months ago. Last week I was changed to T3 Liothyronine, 20mcg twice a day, 12 hours apart. Since taking them the muscular pains have eased but am experiencing severe headaches. Wanted to know, if it's possible, is there an equivalent from T4 to T3 in terms of dosages? Has my dosage remained the same or has it been increased or lowered? Has anyone experienced this before? Thanks in advance!
