Hello, I Have Recently Had A Heart Attack And A

Hello, I have recently had a heart attack and a stent placed in the Right coronary artery which was 85% blocked. Also have long term diagnoses of severe asthma, bronchiectasis, and pulmonary fibrosis. Occasionally I experience severe headaches which were called cluster headaches and migraines- not often, but they are horrible when they occur. My doctor states it is tricky to medicate the headache. What if anything would or could you recommend? Thank you,
