I Am A 69 Year Old Female In Otherwise Good

I am a 69 year old female in otherwise good health. I started having migraines with Aura 7 months ago. Started taking Varapamil. Doctor thinks it is related to HRT and menapause. I had a hysterectomy 30 years ago and have been on estradile/HRT since. Stopped taking Estradile tablet 3 months ago and started taking estradiol .25 gel cream which I rubbed on thigh along with taking Verapamil (moderate constipation side affect). Switched to Metoprolol Succ ER 25MG tablets (moderate gerd now) and stopped estradiol gel cream because Aura migraines still periodically. Now taking only vaginal cream Divigel 3x week along with Metoprolol (moderate GERD continues even with Prevacid 2X daily) Last week had another two aura migraines. Blood pressure continues to fluctuate but not usually over 154/80. Typically 129/80 pulse 65. Hesitate to increase Metroprolol dosage because suffering with Gerd even with Prevacid. Requesting information on Migraine and hypertension medicantions that will not affect long standing GERD. I walk regularly. Any thoughts would be greatly appreciated. Signed: "Feeling my age at last".
