Treatment depends on the underlying cause. If abdominal rigidity is due to a muscle injury, rest and pain medicines are used. Other causes need more extensive treatment, such as:
Medicines may cause allergic reactions and stomach upset. Surgery may cause bleeding, infection, or allergic reaction to anesthesia.
Treatment often stops when the person recovers and the rigidity goes away. The condition may be cured for good, as it is when the appendix is removed with an appendectomy. In more serious cases, death may occur if treatment doesn't succeed.
The need for monitoring depends on the underlying cause of the problem. Symptoms are followed, and physical exams may be done. Urine tests, blood tests, and X-ray tests also may be needed to monitor the condition. Any new or worsening symptoms should be reported to the doctor.
