What can I do to recover better after lumpectomy and reconstruction surgery?

Hello from Maine! I am due to have Breast Surgery on March 25th. I am having a lumpectomy, 3 Lymph Nodes removed, then reconstruction and lifts in both breasts. I don’t handle pain well since I also have Fibromyalgia. From people who have gone through this, can you please tell me what I can do to make the post-surgery go better. Any helpful hints? I have friends bringing me food, another one is taking care of my nine pound golden Havanese sweetest dog for a couple days after surgery. I am thinking of getting a wedge pillow. Anything else? Please give me a”Been There, Done That” here is what worked for me advice. I will do 3-4 weeks of weekday Radiation after the wounds close. I also will have 9 IV Immunotherapy injections three weeks apart. But, my aggressive Triple Negative Breast Cancer was found early by a mammogram and I have “A High Cure Rate!” So grateful, but I am not enjoying being bald.
