Brief Answer:
The TSH value is normal, but on lower side

Detailed Answer:

Welcome to HCM. I have gone through your question and understand your concerns.

The TSH of 0.84 is normal (normal range in most labs will be around 0.4 to 5 miu/ml). You can check the thyroid hormone levels (Free T3 and Free T4) to see if the symptoms of dry skin and lethargy is related to thyroid disease. If that is also normal, nothing need to be done.

Depression and medicines for depression usually cause change in thyroid hormone levels. So don't make decisions based on single TSH values. You can repeat the test after 1 month and decide.

Subclinical hypothyroidism is when thyroid hormones are normal and TSH is slightly elevated (between 5 and 10 miu/ml). Subcinical hyperthyroidism is when thyroid hormones are normal and TSH is slightly decreased (below 0.4). You don't have a subclinical disease.

Hope I have answered your question. If you have ant further questions I will be happy to help you.

My pcp checked me for hernia last week then referred me to a surgeon. I had hernia surgery 2yrs ago, where the surgeon used mesh to repair the hernia. My pain is on the same side as my first hernia. The surgeon checked me today and felt there was no hernia, and ordered a ct scan in avfew days. He seemed concerned though with my pain and it's location. The pain is directly over my first surgery site, it's deep and aching and travels down in my right testicle. I feel very nevous about what it could be, if it's not hernia. Are there any concerns of a mass or tumor or cancer? Is that why he ordered a ct scan? Also I've had 2 spinal fusions L4-S1 and a spinal stimulator implant in the last 3yrs. Any chance this issue could be related to my back issue? I'm 33yrs old... My apologies for all questions, but I'm concerned this is something more serious than what I thought...

For the past 2 plus years I have had a flat red rash that starts on my neck and works it s way around the whole of my neck. It becomes hot, sore, and can be there for days. When it does go down I can pull little bits of skin off - a bit like sunburn . It s appearance looks a bit like I have been burnt. The skin can become taught. It can come and go on it s own accord. It normally starts when I feel my neck tingleing and some timed it can be itchy - quite itchy when it s completely around the whole of my neck. The doctors haven t been able to advise what it is and just tell me to moisturise it.
