OK, I was wondering why your only symptom was the burning.

Multitasking is not good, even for a healthy brain. Research proves it. Try to break your multi-tasking into separate jobs. Complete one at a time or stop one temporarily and take up another. It can help to make a note, "I need to finish doing xyz when I get back to task M" The struggling brain is stressed to remember two separate concepts/tasks at the same time.

It will help to reduce stimulation while your brain recovers. You favorite music may be too much stimulation right now. Some TV shows may have too much visual action that, combined with the sounds, overtaxes your brain.

When doing paperwork, it can help to only have one sheet of paper visible at a time. Multiple sheets can be too much visual stimulation. I even had to use blank sheets to cover parts of a form above and below where I was filling in fields. If I saw a whole page of blank fields to fill in, I would get overwhelmed. You can experiment to see what works for you.

I watch TV with headphones. Otherwise, the sound echos in the room and I struggle to understand the dialogue.

These symptoms are very common. You can push against them and get things done but it will slow your recovery. Reducing stress with daily tasks will give your brain the break it needs to recover.

Just remember, If you brain struggles with an activity or task, it is your brain saying, "I am not ready for this yet." It can be difficult with the busy lives many try to live.

My best to you.
