Hi,
Did you also arrange to see a psychiatrist or psychologist to support and advice you about your health anxiety?
Please keep in mind that if you are dealing with insomnia and aren't sleeping well because your anxious thoughts are spinning and spinning, the sleep deprivation and or poor quality of your sleep is going to be affecting you physically and psychologically during the day...
Anxiety excites your sympathetic nervous system in the same way as hormonal fluctuations, which can cause your body to heat up and cool down, heat up, cool down etc, so if the overheating isn't due to your bedding or room temp being to warm because it's summer, it's possibly associated to your high levels of anxiety at the moment.
btw i was confident i knew what a hot flush was but it wasn't until i actually experienced one first hand last year that i realised hot flushes are only somewhat like what you read about, in reality whoo baby......the heating up is only from my shoulders to the top of my head and it is a surprisingly intense heat, closest i can explain it is your feeling normal and the next minute you're sticking your head in a furnace, and then for kicks and giggles your inner temperature controller is cranking up the heat, and then cranking up the heat some more, and cranking up the heat.
On the outside I look exactly the same and nobody would know looking at me because i don't even sweat or go red faced, hubby tells me he can feel the difference in my temperature when it skyrockets....hmmm i once seriously considered stripping down to my undies and diving head first into the closest produce freezer lol lucky hot flushes typically only last for 1-5 minutes or i might of done it too :D
In regards to your concerns about MS heat intolerance, the technical term is Uhthoff's phenomenon (also known as Uhthoff's syndrome, Uhthoff's sign, and Uhthoff's symptom) is 'not' the same as what you've described....."In general I noticed I am a bit more sensitive to heat. but its summer hear and VERY hot so it could just be that. I do go in hot tubs shower ect and I’m fine after those (i heard MS can affect that)".....Uhthoff's is the return and or worsening of neurological symptoms when the body gets overheated either from external or internal temperature eg hot weather, exercise, fever, baths, showers, saunas, hot tubs, UTI's etc etc.
I hope that helps.......JJ
