Difficult to say without evaluation.
Further evaluation of the bladder can be considered with a cystoscopy and urodynamic studies. This can evaluate for any anatomical causes, as well as functional bladder diseases that can lead to spasms.
Imaging with an ultrasound or CT scan can be considered.
If the initial tests remain negative, a potassium sensitivity test can be considered to look for interstitial cystitis.
A referral to a urologist is recommended.
Followup with your personal physician is essential.
