F or the past 8 days i've felt like i have a rageing fever, I sleep in a winter jacket, socks, etc. I havn't been able to leave my house. Yet, when I take my temp it's 95.8. No sore throat, no ear ache, no cold, nothing. I can't eat and I havn't had abowel movement yet this week. Also, heartburn so bad it feel like knives sticking in my chest. I take advil every 4 houirs and I just go from shivering to sweating. Should I go to the emergency room
