Hi, !
Those pains could be related to MS or they could not be. It's hard to say. You didn't specify where you were experiencing those stabbing pains (and you don't have to tell us), but I wanted to share just one of the many articles we have on the topic of MS and sex -- https://multiplesclerosis.net/living-with-ms/sex-women. It discusses some of the obstacles a woman may experience trying to have a fulfilling sex life while also dealing with MS. And, as you will see from the number of member comments at the end of the article, this is a popular topic of discussion here!
If the pains continue or worsen, you may want to bring it up with your gynecologist.
That said, I hope this was a one time thing and that you and your husband are able to fully enjoy your physical time together!
Best, Erin, Team Member.
