Hi ! Good evening. I am Dr Shareef answering your query. If I were your doctor, after a clinical assessment of the lump and a general examination of your husband including his blood pressure measurement, if considered necessary would advise him for CT scan of head to rule out any intracranial space occupying lesion which includes a subdural hematoma or any other neurological problem for his dizziness. Appropriate management would follow after the reports. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
