not sure whats going on. help.

For the past week I have had sudden scalp burning and pain. Im experiencing hair loss now as well, only on the back of my head... My stomach has been getting sharp pains, I lost my appetite, theres also a burning sensation on my left side under my armpit area, and chronic fatigue. No matter how much or little I sleep, Im still exhausted. I am not sure whats going on or if I should go to a hospital. My doctor is booked up until the end of the month and these symptoms havent gone away and feel like they are getting worse. I work 2 jobs so its hard to take time off. I dont know why this is happening. I might go to an emergency clinic near my work tonight. I dont feel like myself :( EDIT: i started a new birth control last month and my mom is currently in the hospital. idk if it could be a combo of stress and hormones?
