Heavy Pain In Hip, Inner Thigh, Leg. Lumps Near Pelvis. Need To Worry?

Hi am 29year old active female, i was training for a big swimming race and started having pain in my left hip and inner thigh, i wend to chiropractor who treated me for a micro tear in my hamstring . I swam my race and it has gotten worse. Have pain into left pelvis and sometimes down leg with a burning sensation. Went to see her again earlier this week and she ultrasounded the spot on my pelvis but told me there were some lumps i should get checked out. The next day and since then i have been in agony in pelvis, lower abdominal area and only anti inflammatories work for a while then pain comes back. I went to Gp on Wed who said I might have Hernia but have to wait for scan on Monday. Anyway today the pain was worse and the bumps i felt are now painful to the touch and abdomen swollen and have no apetite, Gp sent me to General surgeon who did an examination and told me i haven t got a hernia but must still have my scan on monday. I am in much more pain now that he had examined me. I have 2 children, i gave birth to them naturally, so no c section scars, I have had my period as normal last week although it was slightly lighter than usual. I am so confused and worried to wait until Monday incase its something more serious.
