Hello! I understand your concern! I would like to explain that it is very rare for a shwanoma to cause headache and fatigue. These symptoms can appear after many years with a shwanoma, when it has grown in huge dimensions and compresses the surrounding brain structures. The main initial symptoms caused by a shwanoma are hearing loss ( difficulty in speech discrimination), which is typically noticed when talking to the phone and dizziness and gait problems. Later facial numbness appears and headache. I would like to know the dimensions of your shwanoma when diagnosed. These tumors grow very slowly and it takes years to manifest a full clinical scenario. So I think that the balance issues may be related to the shwanoma. But the headaches and fatigue are more probable to be caused by the repeated concussions. Hope to have been helpful! Greetings! Dr. Aida
