I have problems gripping and with motor skills using my hand: buttoning buttons, zipping zippers, my handwriting is ridiculous. I never had pain in my hands - Just numbness and weakness. I had pain in my wrists, shoulders, neck, and arms though. I went to two neurologists who told me opposite things. They both agreed that I have TOS, but one told me to live on pain meds, and the other one told me I was atrophying, and I needed to do something (surgery.) I have neurogenic TOS, but my vascular surgeon told me I don't have any arterial or venous blockages, but if I continue to go untreated I could develop them.
I started this TOS journey in August (after I was misdiagnosed and misoperated on for carpal tunnel) I finally have peace knowing my plan of action. My advice: Do what you need to do until you find peace. Advice I was given and what works: go with your gut.
