Thyroiditis?: If you are referring to autoimmune thyroiditis ( hashimoto's disease)- this at first can cause an overactive thyroid ( hyperthyroidism) followed by decreased thyoid function ( hypothyroidism).

I have hashimoto thyroidism, pituitary tumor, seizures, lesion on my brain and had multiple concussions. My calves are hurting bad what could this be?

Wow- a lot!: This can either be as simple as muscular if you have had any changes in excercise or even trauma (fall, seizure). Or it can be neurological, neuropathic pain due to your comorbidities or even the brain lesion. Or vascular such as a DVT or blood clot in your veins. I would recommend that you get evaluated at your earliest convenience. ...Read more

Does the removal of thyroid nodes effects on the function of the brain?

Please define: Hi. There are thyroid nodules and lymph nodes, but not "thyroid nodes". However, removal of neither thyroid nodules nor lymph nodes will affect the function of the brain.

The Dr. is probably : Referring to her TSH (thyroid stimulating hormone) it is the brains signal for the thryroid to make thyroid hormones. E=when the thyroid hormones are produced the TSH drops. We call it a feedback response. We use it as a measure of how well the thyroid is working and how well tretments work. However, many things can make you tired. See your doctor and start with a good physical exam. ...Read more

Why do I feel light headed a lot. Shakey sometimes. Feel brain fog. Had blood test done all back good. Thyroids. W-b-c count. Vitamin d?

You may need neurological and cardiovascular exams too. ...Read more

I went to visit an endocrinologist. I do not have erections anymore. I went because I have low thyroid. What can he do for me. I also had brain cance?

I  went to visit an endocrinologist. I do not have erections anymore. I went because I have low thyroid. What can he do for me. I also had brain cance?

Good move: I admire your courage through a difficult illness. I suspect there's been damage to your hypothalamic-pituitary axis, but i'm not the one to say. The endocrinologist will pick other illness -- prolactinoma and hemochromatosis often cause secondary erectile dysfunction in teens and young man. It's much more likely than not that a treatable cause will be found. ...Read more

Could brain fog (forgetting what to say while speaking) be a result of social anxiety? all blood test fine including thyroid and i sleep 8hrs a night

Perception problem: Think about what social anxiety means. Generally feeling nervous in social situations, you are probably thinking about what others think of you rather than focusing on the other person and what you're saying. I recommend that you join Toastmasters for some experience speaking. Another possibility is taking a Dale Carnegie course. A psychiatric diagnosis and meds are not the answer. ...Read more

Possibly: Hypothyroidism if present is best treated with synthetic T4 levothyroxine Synthroid There is variability in absorption and distribution of generic T4 vs. brand names Also variability in generic formulations of pure T3 Cytomel, (liothyronine) T4/T3 therapy may have some advantages over T4 alone.
