Sweating cause. Which test is better?

Hello respected doctors. I am facing this sweating issue while walking but not while sitting in my room. It always start from forehead and scalp. I don't sweat under fan or AC. My normal or heavy sweating stops when I come and sit in my room. I had my blood sugar checked. Hba1c 5.0. I'll have my thyroid checked sooner or later then I'll report here. But can it be something else? If yes, I'll have it checked too and report here.                                                             N this message is for Dr. Manas chopra. 1st, try to understand the query and read it to the end. I didn't say no to the test. I said I can't go for it due to lockdown. I did say I don't have most symptoms. So what? I don't rely on Google I am not that stupid. But it won't hurt me to search. I found practo due to google. Blame Google again too. Still I asked for which test is better? Thyroid free or total. But your ego comes first to answer. And with due respect , NEVER EVER CALL ME KID again. Thank you.
