Ankle Injuries

[lora j]

hurt my ankle three months ago I have had three xrays a bone scan and now an emg the neurologist that did my test was pretty sure that i have rsd my leg is red it was very sensitive to anything touching the foot I have also experienced drying out bad between my toes swelling and weird fillings in my foot plus loss of motion. They are saying its also tarsal tunnel syndrome and my question is they want to do a cortisone shot will this make the rsd more pain full .I am just confused they also just informed me in two weeks they are going to terminate my job after 15 yrs. I need help
