L'Hermittes Sign (Leg tingling) After Radiation

Hello All! 

      i'm happy to say that I finished radiation for NHL in August and have since been in "complete remisson"! With that being said, lately I've been experiencing a mild tingling in my legs, hips, and lower back when I exercise or tilt my neck down (AKA L'hermittes sign). Has anybody else experienced this? It has been confirmed by my radiologist, but I understand it's relatively uncommon. I am trying to figure out what kind of physical activity is appropriate for me and whether or not it will hinder the healing process or if the symptom is simply just a nuisance. Any advice?!
