I was in the hospital a number of times with serious cellulitis of my lower legs. The beginning of it all was I passed out at home, got a concussion and some stitches and nobody could figure out what was causing it. One doctor thought it was possibly vascular.I saw my cardiologist, Dr Sheri Koplick , also a wonderful doctor, and was diagnosed with orthostatic hypotension. It was after that I saw Dr Kawanishi ,who is in the same office. I cannot recommend this doctor highly enough. He had an ultrasound vein mapping done of my legs and some specialized test involving the chambers of my heart looking for a defect. There was none. However he did find some deep veins that were impairing the blood flow back to my heart which is why I passed out. i am still recovering from the concussion and have balance problems for which I am getting therapy. I use support hose and a cane and some exercises he recommended. I can't thank Dr. Kawanishi enough for how well he explained things to me and patiently answered my questions. I would recommend him without reservation for any vascular problems you might have. read more
