My 8-year-old son has been experiencing intermittent headaches for the past couple of weeks, mostly in the late afternoon or early evening. The headaches are not severe and do not require medication. He is very active in sports, and we are keeping him well hydrated due to the hot weather. He recently started wearing glasses and has seasonal allergies with sneezing and a runny nose. We are concerned about a possible brain tumor or other serious health issues. Does this sound alarming?

I had a concussion three days ago after tripping and falling onto cement. I felt nauseous and dizzy the day after the fall, but now only have a mild headache and a tingling sensation in my arm. The arm that hurts is the shoulder that broke my fall. What could be causing the tingling, and should I be concerned about it being a sign of a more serious issue like paralysis?

I have constant hard flutters of my heart, which happen at least 20 or more times every day. I am a 22-year-old female with no family history of heart disease. I have no loss of consciousness, no breathlessness, no chest pain radiating to the left hand or jaw, no excessive sweating, no swelling of the feet, and normal urine output. The palpitations are not caused by anxiety but worsen it. They occur regardless of my position (laying, sitting, standing, or walking) and have lasted for about 8 months. I am scared and looking for relief or a general idea of what could be going on.
