Thanks for the query to H.C.M.. Forum.
You didn't mention your age and sex as these two parameters were very important for evaluation of any diagnosis .
Any how I will try to reply , as this pain is very sharp and only on the right side of abdomen may be .
acute or chronic . Diagnosis can be confirmed by ultrasound
2 Right renal stone . usually this type of pain present due to stone in urinary tract
system on the right side. Get in ultrasound of abdomen and with emphasis over whole of urinary tract system.
3 If you are a female and age is around 20-30 years may be due to ovarian cyst
. Ultrasound of ovary of right side will confirm the diagnosis.
In my opinion the best way is get in ultrasound of abdomen and consult a primary care
physician and get his opinion.
Good luck. Dr. HET
