I am 3 weeks and 2 days post thoracotomy and had the same experience. I was definitely uncomfortable esp at night but all I had for pain was Tylenol. I couldn't even take ibuprofen because I am on a blood thinner. By post op Day 9 or 10 I had a lot of pain. Got gabapentin which helps. Now I'm feeling pretty good but am very tired...of course the weather isn't helping. I'm in New England where we have had constant rain and cold. Weather effects moods and energy. Praying for some sun and warmth.
