"My reaction was unusual! After the second week I began to get daily severe headaches and raised temperature, after the third week my temperature was quite high, still severe headaches, doctor thought it was an infection, blood tests showed extremely high CRP, ESR and raised liver enzymes, also extremely low blood pressure. I was taken off sulfasalazine and treated with antibiotics, improved quickly, recommenced medicine and had exactly the same reaction within aweek!"
