After this last migraine I had (about a week ago), I actually had somewhat of a postdrome phase. Fatigue and irritability afterwards, but most notably I’ve had what feels like enlarging and constricting of blood vessels in my head intermittently accompanied by mild pain. It’s not that bothersome, but I just wonder why it’s happening. It feels like almost the beginning of a migraine when it happens, then goes away within seconds. For some peace of mind, I asked a doctor online (on those websites where you can pay to submit a question to a doctor and they respond within the next few hours). One of them gave me this response, which I believe is fairly accurate:
Hello,
Thanks for posting your query.
The minor spasms that you are feeling is likely to be a milder form of migraine that has persisted after the attack is over. This is not a worrisome finding and the symptoms are likely to subside on their own in next few days.
For such symptoms, try these lifestyle modifications:
1) Go to sleep and wake up at the same time each day. Do not skip any meals and since the headaches worsen after eating food with white flour, avoid taking it in diet.
2) Exercise regularly (daily if possible) and limit stress through regular exercise and relaxation techniques. Yoga and meditation will also help.
3) Avoid bright or flashing lights and wear sunglasses if sunlight is a trigger.
4) Identify and avoid foods that trigger the symptoms by keeping a headache and food diary and limit caffeine consumption to less than two caffeine-containing beverages a day.
5) You can also try over the counter pain killers like aspirin or acetaminophen. If still the symptoms persist, then please consult a physician for specific anti-migraine therapy (triptophans and ergot preparations).
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
