I do too. My husband is always chattering away to me and asking questions and when they're not necessary, I just have this feeling as if I'm just too tired to answer. As if I need ALL my energy, including the energy used to speak.

I find myself saying to breathe think it's from holding because of pain

Does it feel like things aggravate your throat or vocal cords? Things like too much talking? Or breathing deep? I don't know, it's weird.

I can tell different in voice at times especially when in pain

Yes, it happens to me
