7 years ago I was diagnosed with Graves. I was allergic to PTU family so RAI was done. Difficulty with thyroid drugs and have been on a multitude. T4 the worst. The last 2 years been on Cytomel 25 mg and Thyrolar 60 mg split 1/2 in the AM and 1/2 in PM. Due to weight gain, hair loss,puffy eyes, and good/bad days new endocronologist perscribed Synthroid 137 mcg. After a week started having chest tightness, dry mouth, difficulty breathing. Called the doc. He reported nothing to do with thyroid med. Symptoms intermittant at first.In 3 months endo prescribed-Synthroid 100, 88 and 75 mcg, then Lovyxl 88 and 75, then Unithyroid 75 mcg. Symptoms increased and more frequent. I requested to put me back on Thyrolar 60 mg 3 weeks ago. Thyrolar backordered so starting Armour 60 mg today. Presently 3 ER visits and 1 hospital stay later. Heart stress, scans all fine. O2 consistently 98-99. MRI fine. Episodes lasting up to 4 hours. Always come down (systolic 200) w/o intervention. Have bilateral mastoid mucositis infection (1st time). Amacocillian did not work. Another 10 ten of Levaquin. Last day today and appears helpful. Hospital results 4/28-5/1. TSH 4/26, 1.61, 4/28, 1.53 and 9.8 4/28 recheck. 4/22 TSH 5.12. T3 uptake 33, T4 uptake 6.6. Always healthy, active other than thyroid. This is becoming dibilitating-loosing work, in hospital for daughter's wedding.Is any of this related? Would appreciate any insight and help. Thank you.
