Hi doctor. I am a 27 year old lady, ht 5,1", wt. 56 kgs. . My menstrual periods are normal. Last menstrual period however lasted only for 2 days, whereas my usual duration is 4 days. Recently I have been noticing swelling of my face and both feet especially in the morning. There is also a reddish rash on my skin, which is not very itchy. The rash is not raised from the skin surface. I have been taking an anti allergic (levocetrizine) for the last three days. Please help.
