Right Ankle Pain

Hello, first off I am training for my first ironman in cozumel. I am about 7 weeks into my training and I am experiencing pain in my right ankle. The pain is on the outside and I noticed a little discoloration as well. The thing is I have no pain when walking, it is not painfull to the touch and I have no pain when riding my bike. I have new shoes and got them at a running store that that measured my foot, my arch and even video taped me while running on a tread mill. I have had the shoes for a few months and never had the pain before. I have even tried my old shoes to see if the pain would go away and it is still there. I am really not sure what is going on. Any insight would be helpful. I could muster through the pain and keep running but I really don't want to damage anything. Would it be ok to keep biking and stop running for a week or two?

Thanks
