I have a persistent column of small red bumps that start at my sternum and stop at my belly button. They don t itch, but I ve started getting extremely nauseated with migraine headaches. I recently noticed that the bumps have increased/thickened since I ve been nauseated. On any given day in the last year, I could have a line of five bumps. Now, I have about twenty. They are not all over my stomach, but actually, are close to forming a line. Is there any correlation? I went to a doctor about a month ago because I woke up from my sleep nauseated and vomitted. I felt fine the rest of the day.I was surprised when I was given medication for allergies. Could the persistent nausea be a result of allergies?
