I Experienced Pain Of The Sciatica Nature Left Leg Thigh,

I experienced pain of the sciatica nature left leg thigh, knee pain running down to my ankle top of foot. My MRI did not show any disc involvement. but the pain is still in my entire leg from my buttock down. They did say I had hamstring tendinois. since it takes so long to get in to see an orthopedic doctor my inclination is to cancel, but tonight my let is burning red and swollen. Could all of this just be the tendinois?
