In all probability there is some infection in the blood vessels (phlebitis) or in the lymphatics (lymphangitis). It can also be an infection under the skin (cellulitis). Infection can also build up under the scar of surgery and this may need to be drained.
I suggest you re-consult the surgeon and get this examined. At times, clinical examination is enough to diagnose this. Lymphangitis or phlebitis may at times need color dopplar for diagnosis. Take care!
ok you need to calll the dr that performed the procedure obviouly he did not do his job telling you if that is normal or not if you cant get ahold of him soon enough just call a nurse youll be surprised on how helpful they can be
