@blearyeyes Hi, thank you for your comment. I am sorry you experienced that. Unfortunately for me I don't have an answer yet. I had a normal lumbar MRI with no abnormalities noted at all.

Kat, I get similar sensations around my abdomen. It feels like my muscles get tight in my lower back and in my abdomen. It feels like someone is giving me an uncomfortable hug.

I also forgot to mention I've been having extreme heat sensitivity for the past few months. I've had all the tests to rule out things such as hyperthyroidism etc. I will have hot flashes and start sweating from the central area of my face profusely.
