I am not sure if the steroid shot I received in my foot in February 2005 was Kenalog or not. However, In the past 3 weeks I have a light color streak halfway down my foot from the toe almost to my leg. Near the 2 & 2rd toe there is a deep indention. I saw my primary care doctor today and she basically was taking up for the podiatrist who shot this steroid in my foot. I told her he never told me I would have this type of side effect or damage to my foot as a result of getting the steroid shot to relieve pain. This happened at a VA Hospital. Does anyone know if I can sue the government or that doctor?
