What interstitial cystitis can involve
Interstitial cystitis, also called bladder pain syndrome, produces the symptoms of a urine infection without the infection. Pain that builds as the bladder fills, urgency, needing to go constantly, and waking through the night. Because the tests come back clear, many people are treated for infections repeatedly before anyone uses the right name.
It shapes a day quietly and completely: how far you will travel, how long a meeting can be, whether you drink anything before leaving the house. Recording frequency and night waking as they happen gives a urologist or GP something firmer than an estimate, and gives you something to point at when tests keep coming back normal.
