For me it is a heavy, full pain in the whole pelvic area and more specifically by butt... My whole body feels shaky and weak, and I get very dizzy. Sitting or reclining is usually what helps the most. If I try to push through the pain, I end up fainting or being in debilitating pain for a full day or a few days, but even while taking care of myself the pain will last several hours. It always feels very emotional as I instantly regret having sex and feel guilty for feeling that way.
