Pupils, aneurysms, Horners, and headaches ... Oh My!?

Honestly...you had the best test to see if you had a brain tumor. If the MRI showed nothing, I wouldn't worry. The CT scan the same. Your lungs are clear, why are you worrying? I think your worrying is bringing this on. Why in the world are you seeing a PA rather than a real doctor? PA are not doctors and if this warrants a doctor, then that's who you should see. Personally, I don't think you need to see anyone. Maybe an eye doctor but even that can be caused by stress. You most definitely can get a pinched nerve from heavy coughing. Coughing this time of the year is very indicative of allergies. Allergies this year are the worse. It doesn't matter if you never had the experience at all because allergies can attack at any time during your life. You need to stop worrying and when you do, I believe a lot of these symptoms will go away. Good luck
