I am a 33 year old female. I am currently taking bactrum that was prescribed for a chest cold and fever. I had to stop taking due to dehydration cracking lips, a red rash All over my body including painful welts on the outsides of my elbows. The most important question I have is Why I am spotting. I had a hysterectomy in 2005 after having Guillian Barre Syndrome I could no longer have any children . I am very concerned because I have NEVER spotted before. An answer would put my mind at ease. My GP is not in office today. Thank You
