[|Human|] Hi. I cannot help being constantly tired.  It doesnt matter how much I sleep, I will always be tired.  If I go straight home after work, I always find myself falling asleep without knowing it.  Also am always cold (especially my feet) and frequently have headaches.  I am slightly overweight, but eating very healthily and still find weight going on rather than off.  Dont know if this could be related, but every few weeks, I go for a few days with very bad back ache between my shoulder blades.  Would be great to get some advice, I am covering for 2 people at work just now so dont have time for a doctors appointment.  Thanks
[|AI|]  Dear patient You are showing all signs of hypothyroidism. But it could be due to deficiency of vitamin D and calcium. So you need to be investigated with 1. Serum level of TSH, T3, T4 levels 2. Serum level of vitamin D3 3. Serum level of calcium, phosphorus and alkaline phosphatase.  Visit reputed lab nearby you and get this done.  Take visit to endocrinologist with report. Do not neglect your health and do this asap.
