I am 42, cut with a Stihl 250, and have been experiencing tingling in my hands and forearms for awhile now (3+ years) I am not sure cutting wood is the root cause, but it surely is not helping. The tingling isn't bad or particularily annoying, I just don't want it to become debilitating. Are certain saws better than others for lower vibration levels (a cause for carpal tunnel syndrome and a couple of other syndromes causing tingling)? All Stihls have anti-vibration, but are there certain models that are better than others? Do the pro-saws vibrate less? I do, by the way, wear arm braces at night to prevent hand curling and have seen a doctor. I cut once every two weeks or so.
