Does anyone also experience very tight muscles on the side with migraine. Like tight knots that start in shoulder and travel down back. Even causing nausea.

Hello , I'm sorry to hear that you're dealing with this. During a migraine attack people do sometimes experience muscle tension, although typically it's in reference to the head, neck, and shoulders, like with tension headaches, https://migraine.com/headache-types/tension-headaches. I hope some of our community members here can share any personal experiences they have with this type of muscle tension. Have you ever had a chance to speak with your doctor about this? -- Warmly, Christine (Team Member)
