Recently I've realised that when I'm at my own place, I feel more energised, even during this heat. But when I'm at my brother's house, I feel worn down and exhausted. I noticed his house is much older than the newer developments, and it seems to hold the heat differently. Because heat can make my MS symptoms worse, I'm wondering if that's what's happening. Has anyone else with MS noticed that certain buildings or houses make their symptoms feel worse, especially during hot weather?
