I have horrible internal organ cramps. Most are by my ribs. If I cough too hard. I just tried to work out and was trapped on the floor with organ cramps. It's almost like a cycle. Severe migraine headache left side, chronic swollen lymph nodes, chronic sinitus, chronic fatigue, ear pain, joint pain, shaking hands, dropping stuff, trouble saying words or thinking, inflammation in my mouth on the left side. It just starts over. Endless cycle of hell.

Yes, I have it every now and then. On some occasions it’s hard for me to stand up straight. It feels like a tight band. I’m a bit more careful with picking up heavy objects now. Doing so can bring on the pain.

Yes, I have a lot of rib pain. One of my ribs actually sometimes tucks up under the one above it because the muscles knot up. I understand the electric shock sensations, which I believe is nerve issues.

Yes called costochronditis (sp) painful to breathe at times
