Hello; I have had a periodic stinging pain, left side below the waistline for the last 12 hours. The sting lasts a few seconds but returns in a minute or up to 2 minutes later, sometimes longer. At this time, it s an irritation, concern, nothing painful enough to go for medical treatment, but enough I m searching online medical files. The intensity of pain has not increased over this 12 hour period, just this continuous ping/sting. And of course I have travel plans in two days, which adds to the concern of whether this is something that will delay those plans. Thank you, Gloria
