Hello, last night I was awaken by pain in my stomach, around my navel area, got up to use the restroom cause I thought my stomach was upset, later realized that wasn t the case. Went to work, still with the same pain, throughout the day the pain moved to my right side and has since moved to my lower right side. I took my lunch break around 2pm, tried to eat but felt nauseated and I ve had chills and sweats all day. The pain is tolerable but the nausea seems to be getting worse. What do you think is the problem and when should I be concerned?
