[|Human|] I think I have really bad blood circulation because of many reasons. A) I always feel the temperature more than other people. In the winter, Im always cold, no matter how many layers I wear. In the summer, I tend to overheat or dehydrate because I sweat so much (gross I know, sorry). B) My legs and arms fall asleep easily. If i sit still for more than a minute or two, I get really bad pins and needles that take a long time to go away or sometime Ill wake up in the middle of the night because I sleep in odd positions and my arms have been above my head for awhile and it feels as if there is no blood in my arms at all. They feel like Harry Potters arm after that Lockheart guy tries fixing his broken bone - loose, numb, like my muscles cant move anymore, yet my hand and arm functions fine.
[|AI|]  Hello and welcome to Chat Doctor, After going through your query, I am of the opinion that you should get thyroid function tests. Feeling too much cold and too much head is a feature of hypothyroidism. Hypothyroidism is associated with a number of other symptoms like disturbed sleep, anxiety, weight gain, decreased appetite, Chat Doctor. Thyroid function test (TFT) is the first line investigation required. If any abnormality is detected, appropriate treatment can be started. Thanks and take care
