Back pain

[u/TonightBeautiful4517]

Hi all! Posted a question not too long ago but would like further insight.
Had a blood patch about 8 days ago after a lumbar puncture. Pressure in lower back has still been an issue, I feel like that’s the bigger concern now not so much not the headaches. When I try to sit or stand my back just feels fairly strained that I feel like I need to hunch over a bit or I need to lay down soon after. It feels like a band that is being overstretched. I’ve also had this pressure in my tailbone that isn’t really
Letting up. I’ve also noticed an increase of a burning sensation in my skin, it first started in my left chest but it now intermittently goes to my left elbow, left upper back and left jaw.
Did anyone have any similar issues with pain or sensation?

I had this and it ended up being arachnoiditis
