Interstitial Cystitis (IC), also known as Bladder Pain Syndrome (BPS), is a type of chronic pain that affects the bladder.
The cause is unknown. But contributing factors might include autoimmune problems, neurological problems, infection, allergies and adverse drug reactions.
Treatments are currently not able to eradicate the disease, but are aimed at alleviating the symptoms.
“Despite much research and many different theories, the cause is still unknown. While the symptoms may be exacerbated by stress or overexertion, stress itself is not a cause of IC/BPS which is not a psychosomatic disorder.”
