No Improvement After Taking Thyroid Medication. Feeling Foggy Brain, Pain In Neck And Arm. Could It Be Cancer Related?

I am experiencing foggy brain; general confusion; feeling that my brain works slower than it has in the past; aching neck, pains in arms, legs, feet, ankles and hands; feeling cold and hot continually (never normal); sweating profusely when I do even a tiny amount of exercise (eg a small walk); dizinesss; a veer towards the left when walking and general feelings of unbalance; alternate feelings of being hot or cold (often accompanied by so much sweating when hot that I am covered with a thick layer of shimmer); feeling of all over weakness and lethargy. I am told that my diabetes and thyroid are under good control.
Would you have concerns about any other conditions I should be checked for - could it b cancer related or something else undiagnosed?! Does it seem like a thyroid medication issue?!
Thanks for writing in.
If your sugars and thyroid tests are ok with treatment, the possibilities are-
1. There may be episodes of low sugars in between, this may happen with insulin. You may need to check the sugars frequently at home or work especially in between meals. If this is there, then modification of the insulin regime will help.
2. Dysfunction of the autonomic nerves due to diabetes. You can get autonomic function tests done at a specialized lab. These nerves control temperature, sweating, heart rate, blood pressure, etc and may explain your symptoms.
3. Also you should get your blood electrolytes checked as those can also cause these problems.
Please discuss these with your endocrinologist and proceed accordingly. I don't see any need to workup for cancer right now.
Hope I have answered your query. I will be available to answer any follow-up queries.
Best wishes.

Thanks for follow-up.
I see that your iron level is low, probably you have a low hemoglobin as well, which can explain your symptoms to a certain extent.
You should discuss with your physician regarding starting iron supplements.
Regards.
