@timber2026 I was recently diagnosed with PD and have not been placed on any medications yet. I am now learning that many symptoms I’ve been associating with old age (I’m a 67 year old male) are actually symptoms of PD. The hot flashes/chills are a new experience and I haven’t come across any information on this being common with PD. I have also become very intolerant of hot weather ( high 90s and above). I had lived in Tucson, AZ for over 20 years and thrived in the heat. I retired to the White Mountains where the weather is much more moderate two years ago. On a recent trip back to Tucson I was absolutely miserable going outside in temps above 90 and could only tolerate 5 to 10 minutes outside before becoming very uncomfortable, light headed and exhausted.
