Doubt anything serio: Sort lived sharp pains can occur in almost all of us and it is hard to pin point a cause. They usually go away if you ignore them. But any pain which is lasting more than 5-10 minutess and or it is progressively getting worse, requires a check up from a doctor. Without a physical examination, it is hard to tell you what it is. Most likely it is nothing serious. So try ignoring it for a week or two
