Thank you for your question and photos. It is not unusual to have some pain and discomfort in the days and weeks after breast surgery. Pain is very different from one person to the next and you may notice that as you become more active, there can be an increase in some of the discomfort. You should have a follow up appointment with your surgeon, and it is a good idea to bring these things up with him or her as they can then examine you and make sure that all is in order. If the pain increases dramatically and does not go away, you should contact your surgeon for a more immediate follow up visit.
Best of luck.
It is not uncommon to experience pain at different times during recovery. It is great that you were very comfortable during the first week. Sometimes that leads to increased activity earlier than your body can tolerate and pain can increase. It is always important to notify your surgeon with any changes immediately so you can have an evaluation. Since it is on both sides and you have no redness, it is a good sign that it may be just part of the healing process. I would still recommend that you contact your surgeon ASAP to discuss your symptoms.
