Inflamed Thyroid, Low BP near fainting, Migraines & Pulsatile tinnitus

The day before yesterday, I woke up a migraine (about the 5th in my life) on the right side of my head (same side where I have pulsing in my ear periodically), first time having one on just one side, I think. Just the headache, nothing else. The right side of my head still felt weird once the pain itself was better. (I did have a couple of silent migraines 2 months ago also)

I woke up the next a.m. with a pretty bad charley horse in my calf, I got up because I had to pee, found myself holding onto a chair because of lightheadedness, blurry/tunnel vision and feeling close to fainting. I got down on my hands and knees and crawled to the bathroom. I felt nauseous and the blurry vision and lightheadedness got worse while I was urinating and then started having loose stools, I was even closer to fainting. I don't remember how I got back to bed. I have low BP, but haven't come quite that close to fainting except for some mild hemorrhaging during a period. I'm still having some dizziness, some headache, a bit of vertigo or disequilibrium.

I tried using someone's bp cuff and today I measured it as low as 65/39, but it may have been too loose. Usually lately my bp is 80-86/60 and I was able to get one of those readings later on today. My legs still feel tight like they might cramp even though I've been having a banana for potassium, getting some salt intake, and milk for calcium, and drinking water. -the pulsing in my ear is being checked by an MRA in a couple weeks. -I had a carotid doppler that showed my right internal carotid artery has a faster than normal velocity & faster than my left. -I had a thyroid ultrasound that showed my thyroid is a little inflamed (being referred to an endocrinologist) -I'm concerned I'm going to feel this way until I get the MRA.

Can you tell me what might be the problem causing all this. Is it thyroid related?  Is it adrenal insufficiency? perhaps both? How can I help myself to feel better until the MRA comes back at least.

(I was also receiving methylprednisolone injections about a year ago, if that might have anything to do with it.

I also had a stressful driving experience in the winter where I was driving at night in bad snowy weather for about an hour or hour and a half and I couldn't see anything, I wasn't even sure if I was on the right side of the road or if I was possibly going in the ditch.  I was uncontrollably shaking and my teeth were chattering the whole time. I felt like that experience may have messed up my body's hormones or something somehow.  I had a late menstrual period and later I missed a period all together, which hasn't happened to me in quite a few years and I wasn't stressed about anything going on at the time that I didn't menstruate.)

One factor that influences muscle cramps is a mineral deficiency or an imbalance of electrolytes: magnesium, potassium, calcium, and
sodium.  Migraine often occurs as a result of low brain levels of magnesium.  One clinical trial found that supplementing with magnesium caused the complete elimination of migraine pain within 15 minutes in 80% of migraine sufferers.

Normal pulse pressure is around 40mmHg in a sitting position. Narrow or low pulse pressure is defined as under 30mmHg.  Your pulse pressure is 20 to 26mmHg.

Causes of narrow or low pulse pressure include shock, tachycardia, left ventricular dysfunction, hypovolemia, mitral stenosis, severe pulmonary stenosis, severe aortic stenosis, constrictive pericarditis, pericardial effusion, ascites, cardiac tamponade, congestive heart failure, anaphylaxis.

Your symptoms could be related to a lot of different conditions.  We don't usually see a lot of dizziness/nausea with thyroid conditions, but anything is possible.  Your experience getting to the bathroom, sounds more like you  might have gotten up to quickly or possibly and inner ear issue. Muscle cramps can be a symptom of hypo, but could also be a simple electrolyte imbalance.

The first thing you'd have to do is have some simple blood tests done.  You need to get TSH, Free T3 and Free T4; along with those you should get thyroid antibody tests to rule out an autoimmune thyroid condition.  Antibody tests you'd need are Thyroid Peroxidase Antibodies (TPOab), Thyroglobulin Antibodies (TGab) and Thyroid Stimulating Immunoglobulins (TSI).  

TPOab and TGab will confirm/rule out Hashimoto's Thyroiditis and TSI is the definitive test for Graves Disease.  

Did your thyroid ultra sound indicate whether or not you have nodules? Since the ultra sound reveals inflammation, you will need to keep tabs on your thyroid, whether or not it turns out to be the cause of your current symptoms.

Do you have any of the typical symptoms of either hypo or hyper?  

Common symptoms for hypo would include, but not be limited to:  weight gain, high cholesterol, dry itchy skin, dry coarse hair, cold intolerance, fatigue, muscle/joint aches/pains, depression, puffiness (especially around the eyes)

Common symptoms for hyper would include, but not be limited to: weight loss, intolerance to heat, diarrhea, nervousness, fatigue, rapid heart rate, palpitations, warm moist skin, insomnia.

If you are testing blood pressure correctly, and continue getting low readings, you should have a heart work up to be sure there's nothing there to worry about.  Many pharmacies have a blood pressure machine that you can use for free........ you should try one of those (I've found them to be quite consistent and accurate), or have your doctor check your blood pressure.
