Does anyone else ever experience a cool sensation down their spine? It’s so subtle that it’s sometimes hard to distinguish. It’s a bit like a flush only with a cool sensation that starts at the neck and goes down the spine. It happens fairly infrequently and disappears rapidly.
I’ve had this sensation a couple of times over the last month, before I started on Tecfidera. I don’t want to conflate every sensation I experience with symptoms of MS, but I wonder whether there’s a connection.
It’d be helpful to know whether anyone else has experienced anything similar? If you have, whether you’ve received a medical explanation for what might be causing it?
