Muscle soreness after breast reduction 3 months

It would be unusual for your to have pain 3 months after reduction surgery. Most patients find this surgery to be quite easy to recover from and very few have any discomfort after 3 months. It would also be unusual to have muscle soreness after a breast reduction because most surgeons are not disrupting or injuring any of the muscles of the chest during the procedure. Some surgeon perform some liposuction of the lateral chest wall and axilla which I suppose could still be sore. But, follow up with your surgeon will be needed for a better answer.
