Female with no energy

I am a 28 year old female and recently I have gained weight and started to feel very cold even when it is warm outside. I have no energy and feel tired. Is this related to my sinus medications?

 I think you may have an underactive thyroid gland. Go and see your doctor and get some blood work done. The results take less than a day. If you have an underactive thyroid, you may need to take thyroid hormone, which will reverse all your symptoms in no time.
