I m ten weeks pregnant. I have been to the er twice in the last week. Was told I have superficial Phoenician in my upper left arm. They gave me antibiotics. I ve been taking them since the 24th and the pain and swelling is still bad and the redness is three times the size that it was the first day I went in. Now I m just feeling very unwell. I have had this before with my last pregnancy. At that time I was hospitalized and give antibiotics through iv. Question is how long before I should see improvement or should I go back to the Dr?
