Hi there, thanks for asking. Feeling hot and cold while the environment temperature is not so is a sign of constitutional weakness. It could be related to weight loss
and issues with dies you have. Migraine
can also be triggered with this issue. Chest tightness
and some other symptoms of anxiety
can be triggered with stress and anxiety you have during the school. Any method to decrease the stress would be useful. School time is very stressful, and I appreciate it. I wish you a good health.
