Shock wave therapy can have certain side effects. Shock wave therapy typically utilizes strong air waves to achieve therapeutic effects. During the treatment process, it may lead to kidney damage, secondary ureteral stones, and ureteral dilation. Some patients may also experience local tissue redness, subcutaneous bleeding, bruising, pain, and other symptoms. But the vast majority of cases are transient and will gradually improve after 1-2 days of treatment. It is recommended that patients do not worry too much, follow the doctor's arrangements, receive timely treatment, and control their condition.
