Interstitial Cystitis is characterized by symptoms like urinary frequency day and night, dull suprapubic pain relieved to some extent by bladder emptying. The main feature is presence of small hemorrhages on distension of the bladder. Research has proven that symptoms can be worsened by stress, anxiety, depression. So, I advice you to try avoiding these. Pelvic floor physical therapy (PT) may be recommended to decrease tightness in these muscles. This can decrease pain as well as urinary symptoms like urgency and frequency. Some physical therapists will be specially trained to perform this kind of pelvic soft tissue manipulation and rehabilitation. Hope this helps!
