I fell at a Dr s appt on 7-29-14 on knees. DR s office took xrays. Nothing broken, but bruised, since then going to PT & now have had left foot & ankle pain, swelling. Went back to Dr s to re-evaluate. Sent me to hospital to have D-dimer & doppler done. Both tests negative, but I m still having a lot of swelling, pain in left foot & ankle & calf. Don t know if they ve missed a stress fracture? I m debating if I should go to the ER?
