Hello fairly new here, my at a wits ends it may seem and it's driving me crazy thinking its a worse case scenario sort of thing. So I've been going to the doctors for literally months about this jaw pain I've had and sinus issues, dentist said somethings wrong with my TMJ joint and refered me to a specialist, and the doctor has referred me to an ENT for my sinus problems both cause me facial pain and side of my head pain but I now know it isn't a Tumor or something worse causing this pain.... However, recently since this all started my vein has been popping out daily 24/7 and slightly throbbing just above the left eyebrow forehead area down to bear the side of my head and is leaving me extremely worried. Doctors say I have no red flags to any serious medical conditions and I do now believe them... But what is his being I really don't know why it is there could it be caused by my sinisitus and sinus issues? It's hard to pinpoint what's causing what with the sinuses and the TMJ. Any reassurance would be EXTREMELY, appreciated! Thank you! Oh and side note I'm always hot in my face but again I believe that's sinuses. Infact I felt it again, and where the TMJ hurts I can trace the vein near where the TMJ is and all up across the side of my head to above the eyebrow I don't know what it is but it's worrying me
