I'm having dull pressure pain 2 inches above belly button, nausas, sweating off and on, palpable lumps in abdomen and flank area? Just don't feel good

See your doctor. That is a diverse, seemingly unrelated grouping of symptoms. In order to sort it out, you need a good evaluation by your doctor, including a history and physical exam and possibly some tests. I would see him/her soon. Good luck.
