Hi, !
Alene pretty much covered it, but I will say that eventually people can discern what's an MS hug and what's anxiety or a muscle pull. Pardon the analogy, but it reminds me of a first time mom trying to tell if they are experiencing labor pains or not. Once you experience full contractions, you KNOW them. And once you are able to find out if your pain is "the hug", you will recognize it should it occur again. I know that's not really helpful advice, but that seems to be the way it goes.
And, we always recommend letting your doctor know about any new or worsening symptoms, but that can get overwhelming for you when you are experiencing lots of symptoms or EVERYTHING is a new symptom. It does tend to get easier as you and your body figure things out. Of course, MS loves to throw surprises a person's way, too.
You can always call, just to be safe. Or, you can ride it out and mention it at your next appointment, if you prefer. The choice is yours.
I do hope you don't experience anymore of these episodes and if your symptoms ever feel serious and are accompanied by other issues (shortness of breath, crushing chest pain, etc), we do recommend calling the doctor, just to be safe.
