Hi, I went for a run at 6am this morning. Throughout the entire run I had lower abdominal pain on my right side. It was tolerable. Half way through the run my lower back on the same side start to get the same sharp pain but it was still tolerable. By the time I got home the pain increased and spread to my inner right thigh. It is now 3:15pm and I am still in pain in all three areas. I ve had two bouts of ibuprofen. It almost feels like period cramps but 100x stronger. I find finished my period 3 days ago. What does this sound like ? I don t want to go to the emergency room only to be sent back at home. I get the most relief from lying down.
