thank you for the information,
There are some common causes of such abdomen pain on the right side.The common ones are appendicitis, colitis, bowel obstruction, lymphadenitis, diverticulitis, salpingitis, twisted ovarian cyst, etc.
As per the symptoms, the chances of appendicitis should be ruled out first which may cause such pain in the lower right region associated with nausea.
The lymphadenitis and colitis may also cause such pain commonly and should be investigated.
The other cause to be ruled out is kidney stones which may also cause such pain.The ovarian cyst may also cause such pain and should be ruled out.
You need to have the relevant investigation done like sonography abdomen, ct scan abdomen, blood countsm, serum amylase,lipase, etc. to know the associated abnormality after consulting your doctor.
The treatment depends on the underlying cause.The analgesic drugs like motrin , tylenol will help in controlling the pain.The antispasmodic drugs like buscopan, anaspas will help in controlling pain due to spasm.
Let me know if you have any doubt.
