Severe ankle pain can sometimes be a sign of labor, but it is not always the case. It is important to consult with your doctor or healthcare provider to determine the cause of your pain and whether it is related to labor or not. They will be able to assess your symptoms and provide appropriate guidance. Additionally, back pain is common during pregnancy due to the extra weight and changes in posture. However, if you are concerned about the intensity or frequency of your back pain, it is advisable to discuss it with your healthcare provider as well. They can offer suggestions for managing the discomfort and ensure that everything is progressing normally with your pregnancy.
