Pain in my scar!

So it's been a long time since I've posted.  For any who do not remember me, I had a 22 cm tumor on my Right Kidney.  It's been almost a year since my surgery and for the past couple days, the top end of my scar (part that starts on my right Latissimus Dorsi) has been burning.  Today, it freaking hurts bad...I can barely move my arm without feeling the pain. 

Anyone feel this?
