Welcome to HealthcareMagic forum.
As your neighbour suspected, lower right quadrant abdominal pain
with fever is a feature of appendicitis
. If you continue to have this pain, fever with or without vomiting, you need to go the ER to rule out appendicitis.
Other possible causes could be an intestinal infection, diverticulitis
, a referred pain
(source being the renal system).
I hope you are better when you receive this answer. But if you are in distress, you need to visit your doctor at the earliest. Routine blood counts, ultrasound examination and urine microscopy are entailed.
Hope this is helpful.
Wish you speedy recovery
