You need to get the medical records of what happened to you in there. There is usually an anesthesia record also. Call the hospital and find out how to get them.Usually you will have to make a written request. All anesthesia lowers blood pressure. Some people who have complications like that under anesthesia have undetected heart problems.
Anesthesia can affect people badly who have adrenal problems. Adrenal problems can also cause heart problems (but isnt the only cause.) Both adrenal fatuge (Addisons) and hyperadrenals (cushings syndrome or conns syndrome) will get migraines. hypoglycemia usually runs along with it and can also cause migraines (because blood sugar is controlled by adrenal hormones also). Many people who have adrenal fatigue are not diagnosed. They just know that they don't "feel good". Most doctors do not know how to recognize it. Have you had instances in the past where you get dizzy, often when you rise from a chair? Or shakey when you dont eat?
Usually, when a person's adrenal hormones (called aldosterone and /or
cortisol ) get extremely low, they will get nausea, vomiting, confusion, inability to speak, breathing may become harder, chest , stomach or leg pain can occur,they loose blood supply to the brain,vision may blur or blackout, blood sugar drops drastically, blood pressure drops, and they can eventually slip into comatose and /or death if the blood sodium, sucrose and cortisol are not restored to normal levels. so another possibility is you could have gone into shock?
People who have adrenal fatigue usually do not have enough of the stress hormone being put out. so when any kind of body stress happens (illness, exercise, operations, dental visits, menses, birthing, even parties) the small amout of hormone they do have get used up quickly, leaving the body drastically and dangerously low. My daughter slipped in shock after snow sledding one day.(Addisons's crisis.)
The docotrs who are experts in hormones are called endocrinologists. If you do get a blood sugar test, don't do a morning fasting blood test. They can be falsley ok until someone is fullblown diabetic. do a 24 hour glucose tolerance test, which is much more accurate. Testing blood cortisol is not accurate either. Do a saliva test for cortisol. A cardiologist can check your heart.
Sometimes magnesium malate or citrate will help greatly with migraines. 1000 mg is about right....citrate may cause loose stool until the body can get accustomed to it.
