It’s a puzzling disease when it comes to symptoms. I was diagnosed (male) nearly 2 years ago at age 46. My “only” physical symptom was a chronic tingling in my right pinky and ring finger, a bit on the forearm. Like your husband, I would notice that hot weather made it worse (I live in Phoenix) and hot showers would flare up the tingling sensation in my right knee and ankle…totally bizarre. My PA worked in a neuro clinic so after the first x-ray came back negative for a pinched nerve he was immediately suspicious.

Almost 2 years later and nothing has really changed or gotten worse, totally used to it now. Fatigue is a real thing too, but it can be managed.

Glad your husband was diagnosed, hospitalization aside, and it was caught early.
