TWO WEEKS LAYER THE SAME ARM IS SWOLLEN BRUCES HOT RED. I WENT TO ER AGIAN THEY RAP MY ARM ELASTIC BANDAGE.FROM WRISK UP TO  MY SHOULDER. WHICH SPECIALYST I SHOULD SEE AND WHAT RISK IS MY LIFE [/INST] Dear patient. You have acquired thrombophlebitis infection of the vein during iv catheterization. You should undergo complete blood tests and stay for a complete course of antibiotics for at least 1-2 weeks. .i don't recommend using elastic bandage use continuously. It should be untied every 10 minutes to prevent damage to the arm.thombophlebitis is treatable, and it takes some time. Consult an MD IN INTERNAL MEDICINE PLUS A GENERAL SURGEON.BOTH WILL BE BENEFICIAL.hope I have answered your question. Chat Doctor.  </s>
