Two Days Ago I Went To See A Chiropractor. It

Two days ago I went to see a chiropractor. It was my very first visit. After that night I had a very bad headache but I could manage it taking some aspirin. Trough the next day I felt quite tired. When i went to bed I could not sleep because of heaviness in my chest and my stomach. It could not breath properly and had this terrible burping. Now I am wondering if the chiropractor did something wrong or it is some common thing following the procedure?
