“Need advice on my abdomen?”

I ate dinner around 4pm and about an hour later I had stomach ache, however it was very severe. I assumed it was just the food and tried to continue with my day but the pain got worse and over time became focused on the lower right part of my abdomen. I told my family member and they suspected it was indigestion but the pain is sharp and doesn’t feel like it. I’ve had no other symptoms my temperature is normal and I don’t feel nauseous. I took some painkillers and the pain has died down a bit but it is still constant. Deep breathes aggravate it.
