Discolored hard palate, jaw and headache

Female, 26, non diabetic Symptoms since the last one week - Severe shooting pain in my left jaw and TMJ (on and off) along with severe headache. - Bearable but diffused pain throughout the left side of the face, especially behind the eyes (on and off) - Teeth sensitivity is constant and teeth pain om the left is on and off that gets worse during movement. Right side of the face is fairly painless. Developed dark patches on my hand 10 days before the symptoms begin. Pain progressed slowly and I contacted two ENT specialists on practo only to get painkillers whereas Im looking for diagnosis. Pain didn't subside after painkillers. Please lead me to the right course of treatment before I delay, if this could be something serious.
