I have been running about 2 years and have recently slowly ramped up my meleage from about 20-30 miles per week to about 40-45 miles per week. All low intensity aerobic miles with a plan to start in the new year. Mostly off road until the recent bad weather forced me off the trails and onto the roads. Recently got back from a long run with some pain in the side of my left knee. It was noticable during the run but not bad enough to raise concern. However after the run the pain was worse and stayed for a while. Pain goes away and comes back sometimes after sitting and then standing up to walk. There is no swelling or any visual sighns. I can run ok but I have decided to rest as much as I can stand until symptoms go away. I have iced it a few times and I suspect ITBS but not completely sure. Might try a few slow miles at the weekend to see what its like. If things do not improve by the new year I will try a physio. Any advice in the mean time would be great.
