Hello Doctor, I've been sick for almost 25 days now. Had sore throat for few days then disappeared. After it disappear, I got chills, night sweats especially at the neck and shoulders for a week. No more night sweats but the chills and the hot flashes keeps still occur . After that, I'm always dizzy, light headed, always tired and fatigued. No running nose, no coughs, and no sneezing. Recently, my mouth is dry, headaches, and have a skin rash on my right shoulder. No other rashes on my body though. Can you tell what's wrong ? And Should I be concerned ? Thank you
