i woke up today with pain at the back of my neck and even at my shoulders back. I actually did some massage at my back yesterday. I only notice this morning when I took a bath there is a bit pain on the left side of my neck and there is like a pea bean size on it? Is it connected to wrong sleep position or because of having a back pain?
Hello, Welcome to Chat Doctor. Since you already have a back pain you may be having cervical spondylosis. Sleep in an abnormal posture may lead to a disc pinch on a nerve and that can cause muscle spasm and pain. If the swelling persists, you should see a doctor or have a soft tissue ultrasound examination to diagnose it.
