I rarely hear そしたらaround me. I often hear じゃあ、だったら、それじゃあ、それならand so on. It doesn't mean that we never say そしたら. Some people use it often. May be it depends on each region. (?) I think you shouldn't use そしたらto older person than you or not so close friends or your family because it's casual expression. (Some one don't mind but some one care (mind?)about that)
I went to a doctor today and I am in my house now. He said it might take 3 more weeks until my toe will heal up. After taking a X-ray again and he will find my toe is good, then I will be free from a hospital! Yay~👍
