For the past two months I've been having inconsistent lower left abdominal pain. The pain is always in the same place, but is not consistent/constant. Localized to just the left abdomen (my back doesn't hurt). Usually hurts the most when I first stand and start walking. Feels like a really tight muscle that won't let me stand up straight. Pain goes away after I've taken a few steps. If I have exercised it hurts more after, but not during exercise. Wondering if it's a pulled muscle? Appendicitis? Ovarian cyst? I'm trying to get into see a doctor but they are booked until October.
