The pain you describe is likely from a muscle strain and not of concern given your young age, acute nature of the pain, and no family history of breast cancer. Continue to monitor your symptoms and follow up with your doctor if your pain does not improve over the next week. Thank you for using HealthTap for your health related questions!

Probably fibromyalgia and nothing to worry about. Good Luck
