hello doc.. am 24yrs old female, suffering from sero negative spondylo arthropathy,since 4 yrs. which is under controlled manner at present. in the beginning was a very severe condition, almost bed ridden. but recently i developed some stiffness n tearing kind of pain at lumbar spine, during flexion. also i have breathing difficuties, pulse over 100/min. has vertigo very often. Are all theses symptoms related? havent done HLA before. ANA negative, ESR and CRP raised. IS this present controlled situation temporary? sued to tak SAAZ, but now not under any drugs. Is this risk?? Thank you.
