I am currently taking Lisinopril, Ditiazem, Propranolol and levothyroxine. Six weeks ago I had my thryoid removed and felt awesome for about 3 weeks. Week 4 has symptoms returning, ankles swelling, joint pain, headaches, hot/cold intolerance and sometimes shortness of breath. The levothyroxine is at 150mcg and I m wondering if it is too high a dose?
