I have been icing. I did have this treatment about 18 months ago and the Dr. thinks some filler was left over from first time, but not much. I do recall a similiar over swelling but this time it seems extreme. Im uncomfortable and feel unsightly. Please help me determine if I need to return to the Doctor ASAP or if I should wait another 24 - 48 hrs. I do recall more needle injections on the effected side, is this simply vascular trauma that will heal on its own?
