Had Novocaine Injections In And Around Possible Skin Cancer On

Had Novocaine injections in and around possible skin cancer on my ankle, a part of which was removed to biopsy. Afterward, I felt like I had a sprained ankle and today, several days later, I noticed my ankle was somewhat swollen and edemic (I have bad allergies and eczema, and sometimes when my eczema is bad, I get edema in my feet).

What to do?
