Fronts don't bother me but my body doesn't adjust temps in general. I handle cold but if I get cold my whole body seems to lock up. I stay cold longer than most and wear sweaters until it hits the upper 70's or so. I am miserable inside restaurants in the summer, shaking and shivering like crazy.
Once my body decides it's not cold anymore I slowly start wearing lighter clothing. But, when I get hot my muscles get very, very weak. I went outside on a 60* morning to plant some flowers in my garden. I'm talking small plants and digging a small hole for each. I ended up getting hot and literally had to crawl up the steps to my front porch. I don't go much of anywhere during the summer because of it and my pretty flowers die because I can't water them.
Oh, and yes I have different diseases besides fibro.
Riding in the car very far always wears me out and makes me hurt. The hurt isn't awful, just normal like with a flair but the fatigue and weakness that comes over me is awful. If it's hot out and I'm hurting I turn the AC down then turn my heated seats on.
My father-in-law had fibro but that doesn't really mean anything to me, of course. No one else in my family has it. I have read that autoimmune diseases can run in family's. For instance, I have one cousin who has sarcoidosis and another who's body(forgot the name, Otosclerosis maybe.) has attacked her ears and my son has psoriasis.
What if trials of this life are Your mercies in disguise.
