Is it possible to have a groin hernia with no lump? er doc says it felt like one but there isn't a lump. i exercise 5 times a week. on right side.

Small : Small intermittent bulging can occur. Observe over time. They tend to enlarge over time, so do not want to wait til huge!

No Bulge, No Hernia: Both hernias and pulled muscles may cause pain in the groin, worsened by lifting or activity. In general, a hernia is associated with a bulge/lump as well. Ironically, hernias typically cause less pain than a pulled muscle. Did the er doctor examine you when you were standing up and bearing down? I recommend scheduling an appointment with a hernia surgeon for a hernia exam.
