Has anyone else gottena bad wrist/thumb from carrying baby?

My right wrist/thumb has felt strained for awhile now, doc said most likely from carrying baby and could be tendonitis. I was told to rest it, wear a brace, and ice it

I mentioned how tough it is for me to rest it as im a single mom so i have no one else to carry him for me. Ugh

Did this happen to anyone else? What did u do? Did it go away
