Migraine is a vascular headache
& not the routeine headache.The severity of migraine is generally reduced during pregnancy in many women due to the influence of estrogen but in some like you, the intensity is increased for reasons unknown.
Although the severity of your head ache justifies drug threapy, most of the drugs given in the treatment of migraine like Sumatriptan
, procloperazine & ergotamine are contraindicated during pregnancy & this leads to additional difficulty in treating your migraine. So,
1. Identify & avoid triggers like coffee, cakes & chocolate. Avoid stress.
2. Try ice packs, massage.
3. If the pain is severe, Tab. Paracetamol
625mg. Risk is minimal if taken less freequently.
Since you are pregnant, even the drugs given in prophylaxis(prevention) like metoprolol
should be used cautiously & only with doctors advice. Visit your Dr. immediately if your headache becomes more freequent or if it is accompanied by blurred vision
