My mother's right hand index finger was having pain from about month. After that nail start becoming bluish black. On showing to local surgeon he said there may be pus and then put a cut for removing pus. But he didn't found that and told that toe portion of finger is to be removed. We then went to a local plastic surgeon, he said that it is problem of reduced blood circulation in right hand and told to get color duplex doppler of both upper limbs. Report says mild reduced peak systolic velocity at right radial and ulnar arteries as compared to left side. For above doctor have given some tablets. Now finger has become yellowish and is swollen from front. There is pain at the cut mark made by surgeon. Now what to do?
