Hi, may I answer your health queries right now ? Please type your query here...My complexion is getting darker during the winter months here in Michigan and my breasts have been sore for two weeks, I'm not pregnant being I haven't had sex in over a year. In addition, my knees ache each time I rise from sitting on the couch, bed, toilet etc. I plan to see my doctor in the next couple weeks if my symptoms persist orr worses.
