Good morning ! As it appears to me, your lower right abdominal pain is coincidental to your injury.I need to know its severity,do you feel nauseated or have a low appetite or have vomiting.If your pain is quite bothersome ,causes nausea sometimes,vomiting even once and your diet has reduced you are probably suffering from chronic appendicitis.Other possibilities are amoebiasis and worm infestation. Try Metronidazole 800 mg 8 hrly for 7 days and only one tablet of Albendazole 400 mg. If condition subsides well and good but if not visit a surgeon. Thanks!
