I'm sorry I haven't heard of scarring from trauma/accident, but my fallopian tubes were blocked with scar tissue of unknown origin (not endometriosis), part of why we had to do IVF to conceive DS. I had to have a c-section and the scar tissue was gone when my doctor "delivered" my son. So maybe pregnancy does eliminate scar tissue? It is worth asking about or having another HSG. Good luck!
