What if you don't have fever as a symptom does that mean you don't have cystitis?

No relation: Cystitis is an inflamed bladder due to infection that can be painful and it can become a serious health problem if the infection spreads to your kidneys. It may also occur as a reaction to certain drugs, radiation therapy or potential irritants, such as feminine hygiene spray, spermicidal jellies or long-term use of a catheter. Cystitis may also occur as a complication of another illness.
