Hip Bursitis anyone?

So I'm training for the NYC Marathon, which I ran last year in 3:23. I'm a 25 year old male, 160 pounds. I had some patellar tendinitis in my knee earlier this year which I took care of by increasing flexibility and hip strength. Yet, now I'm experiencing relatively minor pain in the high hip socket area on both sides, just an inch or two below my waistline. The best internet diagnosis I can come up with is hip bursitis. I'm already taking anti-inflammatories for preventative purposes with my knee. What does anyone know about this injury? How bad is it? What type of recovery process is there? Thanks so much.
