<s>[INST] Hi, I have just been diagnosed with a disected carotid artery which is outside of the brain area. I had had headaches for 3 weeks before the MRA revealed the disection and I am on Plavix and an aspirin each day. This was diagnosed one week ago. The neuro-surgeon at the ER said that I could travel by airplane next week while my PCP said that i shouldn t. What is your opinion. [/INST] Hi, Thanks for writing in. You have been diagnosed as having a carotid artery dissection and this has been examined in detail by your neurosurgeon. Since you are on Plavix and aspirin, your neurosurgeon must be aware of these medications. Since the ER neurosurgeon has seen you at the ER and found you fit enough for air travel after a week, I think there is no need to worry. I hope your air travel is on a domestic route, and you will not be inconvenienced during your flight. The PCP has given views which are of a general nature and someone having a more serious for of your condition might be asked not to fly. Please do not worry and carry your medical records during your flight and visits. </s>
