I had mt thyroid removed 6 years ago, since then I've been on Levothyroxine. My surgeon recommended I started on 250 mcg daily according to my weight. GPs have always measured TSH, (which I have always struggled to get my head around) and I'm now on 100/125 alternating days. For the last 5 years I've suffered with a breathless feeling like I forgot to breathe and feel I need to really gulp the air into my lungs. Reasons for this have varied from Asthma, COPD to being fat. Over the last year I've suffered with lethargy, aching limbs, mood swings, neck ache, and every evening I get a feeling of pain across my back, shoulder blades shoulders and arms. It feels like I've been battered. Does this sound familiar to anyone? Are there any resources I can access to help me when I see the doctor? Any ideas how I can ease this? I'm being treated for depression with Mirtazapine, and take my thyroxine at night after discussions with a pharmacist.
