<s>[INST] I went to my family doctor yesterday with a poss. kidney stone or infection. I was running a fever as well. I was given an antibiotic shot and pain meds. This morning it is still painful and I am feeling a lot of pressure on that side. Do I need to go to the ER? [/INST] HiT hanks for your query. I appreciate your concern for the fever and abdominal pain. If you have additional symptoms like burning urination or blood in the urine you have to undergo lab tests like urinalysis and an ultrasound to come to a diagnosis. Meanwhile, take plenty of oral fluids, NSAID painkillers like Diclofenac along with Dicyclomine. Hope this suggestion could be useful in getting the treatment for your problem. Rate this answer, if you are convinced. </s>
