Lactic acid feeling and tired muscles

Hey everyone,

Ive been doing some research into this symptom because it’s confusing. My muscles have been getting very tired very easily and they burn/hurt like I’ve just hiked up a mountain after little effort, I even wake up with it. On bad days it even hurts to hold my phone and text. Some of the information I found states that it can be a symptom of dysautonomia because oxygen isn’t making it to the muscles properly and the autonomic dysfunction can cause mitochondrial issues and get the muscles to tap into reserves essentially. I didn’t even search in the context of dysautonomia but this came up frequently.

What are your experiences with this and have you found anything that helps?
