Bladder spasm generally refers to spasmodic contraction of the bladder smooth muscle or bladder sphincter, generally manifested as abdominal pain during urination, incomplete urination, temporary shutting up of urine, etc. Bladder spasm should be treated in hospital as soon as possible, and the following methods can be taken to relieve pain: 1, hot compress: wrap a hot water bag with a towel at a temperature of about 45°C and apply a hot compress to the abdominal area to relieve pain; 2, massage: rub hot hands and fold them on the lower abdomen, i.e. below the navel, then massage in a clockwise direction for 3-5 minutes to relieve pain; 3, oral medication: if the pain is not relieved, oral analgesic or antispasmodic medication can be taken as prescribed by the doctor.
