So i recently moved to UK 2 days back. Here it is cold like 4-5 degrees but we have heaters in room. However, from the day I have arrived here I see that I wake up with excess night sweats, mainly my arms and head area. I don't have any other symptoms except headache when i walk in cold, unilateral headache it is which goes away. Before coming here, I had dine Hba1c it was 4.9, sugar profile was normal and I had also done a Complete blood work. Cbc, lft, kft, thyroid, lipid were normal as wel. Had done usg abdomen, was normal. Idk why it is happening but I am getting scared cause of this. My sleep will break and I will find myself drenched, but when I wake up, its like gone after 4-5 minutes. Please guide!
