Hello, So sorry my dear that you ve been stuck in the head. Your headaches and any other symptoms of dizziness, imbalance, or even nausea/vomiting are likely as a result to that blow to the head by the knee you got tagged with (how did that come about?). If there is ringing in the ear that s not going away or you feel your hearing is affected on the side that took the blow you need to see an audiologist (if not a doctor) for an evaluation. If the headache suddenly gets worse or if the symptoms become so intrusive that they interfere with all your activities then, it is time to get to an ER or Urgent Care center. As far as the other unrelated symptoms are concerned about fatigue and breast engorgement there are many common causes. Proper blood work can help look at some of these issues with correction of things such as a low thryoid profile, anemia, or dehydration. Otherwise, relaxation and deep breathing exercise done daily assist and make you feel better. Breast engorgement often occurs in the context of a woman s menstrual cycle and will subside as the cycle goes through the ovulatory phase and approaches the mense. Again, typically these are not serious symptoms but if for some reason these are different from what you usually experience or if you happen to miss your next expected period then, a pregnancy test may be in order if you are sexually active. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Dariush Saghafi, Neurologist
