I have family history of stroke as well as high blood pressure. is it ok to take sumatriptan for migraine still? also, are the any contraindications for sumatriptan and diclofenac sodium?

Sumatriptan is only contraindicated in patient with history of stroke and uncontrolled hypertension, not for patient with family history of those conditions. Yes, sumatriptan can be used along with diclofenac, a NSAID, but you should use diclofenac as needed only.

Stroke in females suffering migraine occurs more often if migraines with aura plus smoking plus birth control pills. Family history needs mention to your doctor for future possible risks
