Is it possible that my MS is causing instant hot flashes when I am upset or stressed? For example, if a particularly annoying person calls, as soon as I see their number displayed a hot flash sets in.
My initial impression of the connection between MS and an immediate hot flash is dubious. MS symptoms tend not to come on suddenly but have a more gradual onset and also tend to be asymmetric (i.e., not a mirror image on both sides of the body which is usually the case in hot flashes). I think it is more likely a stress reaction independent of MS. With that said, medications such as gabapentin that is used for MS-related sensory disturbances can help hot flash symptoms as well if their severity warrants a medication trial. This is something you can bring up with your doctor. Other option, of course, is to block all annoying callers if feasible. :)
