I didn't realise it could be related to Pelvic Instability, I had it with DD and it has just started again on Friday, had the pains when coughing a lot longer, but no troubles with my hips, groin and pelvis area until just recently (got 6 weeks further before it started this time as well ), but today has been a great day, probably means tomorrow will be a painful one at least i know now how to put my support belt on
