I have abdominal pain on my right side, approxamately in the middle between my rib cage and hip bone. It has been a dull ache for about 24 hours now. It gets worse and better throughout the day, much worse if I lean over to the right side though (such as bending down to get the dogs food dish). I took my temp and it is 99.2F, I normally have a slightly below 98.6F temp for myself. The pain isn't to bad, more of a dull ache with a sharp reminder when I bend down. Could this be my apendix? Is it something I should go to ER about tonight or would tomorrow going to my family Dr. be soon enough?

Doctor will do. If it gets worse then get to the ER.
