Hi, i'm a student physio and 400m runner who has suffered a stress fracture of the 2nd metatarsal a couple of years ago. I continued running through the pain for a couple of weeks as noone advised me otherwise (I was not a physio student then) and have now got a dropped arch and significant scar tissue under my medial arch. I beieve this was because I altered my running biomechanics to avoid pain in my foot, damaging other structured in the process. Anyway the best thing I could ever have done was aquajogging..why do u have a problem with this? When done in the deep end using an aquajogging belt this is not weight bearing, and should not hurt! I have since seen many other athletes with stress fractures of different lower limb bones who have all been advised to keep up fitnes in this manner untill the pain of weightbearing activities subsides.
