pain
"I started taking Hysingla 40 mg about 10 days ago. It does take the pain away about 80% of the time. I wake up thru the night with only about 3 hours sleep.  I also have terrible headaches now. I don't know if any of this is related to my medication as I checked the side effects, but this has only started since then.  You would think taking pain medication I wouldn't have headaches. Talking to my pain management Dr next week."
