I have just started to re-learn trials. When doing a small 2 foot gap seat in, I felt a small strain in my lower back.
The next day my whole spine was curved. It is painful, but the real problem is how awkward it is to walk or sit or bend or anything.
I went to the doctor yesterday. He said it is just a pulled muscle in my back that is forcing the spine to curve. Getting an x ray tomorrow to make sure. Has anyone else experienced this? It is kind of scary.
A simple muscle spasm, the muscle is in contraction, so it has pulled your spine out of alignment, not uncommon. Take some NSAID’s, don’t try to stretch it out, once the muscle relaxes you’ll feel better. Try doing some cross-training
