sudden BP drops and headaches

[hashem]

Hello, in recent months I have have a constant intractable headache 24/7.   It had been moderate to severe at times, but is allways present.  I have had an extensive neurological workup including MRA MRI and CT.   I have also been tested for CBC, TSH, compreh. metabolics, among several others.  

Most recently I've been having sudden nausea, weakness, "internal shakes" (feels like the muscles around my ribs tense up),  sweaty cold hands,  and extreme craving for eating a large meal.    I have a home BP monitor and during these times  I notice my BP drops down to sometimes 100/60  when my BP is almost allways normally around 135/80.   I have also gained about 35 pounds in the last several months with no explanation except for my incresed hunger.   I am a 29 yrold male can you please tell me if I'm at the verge of diabetes or is this something else?  thank you

Some of your symptoms sound like some of the symptoms of hypoglycemia... You might want to try drinking a half to 1 cup of juice when this happens and see if you feel any better in about 15 minutes. Some of the symptoms of hypoglycemia are:

1. headache
2. sweating
3. sometimes no sweating, but sudden cold chill or warm flush
4. nausea
5. feeling of fatigue
6. inability to concentrate
7. shakes -- sometimes in hands, but sometimes in any other muscles in the body
8. dry mouth and/or eyes
9. sometimes instead of nausea, there is a craving for food, especially foods with a high carbohydrate count
10. irritability
11. feeling of unexplained stress or depression

These are only some symptoms that people notice. The symptoms can vary greatly from one episode to another, so any combination of these symptoms can be a sign of dropping blood glucose levels. Most people can get this under control if they do some dietary changes. A glucose tolerance test done by your doctor's lab can sometimes verify that a person has episodes of hypoglycemia, but sometimes the test comes back normal even if the person has very deifinate hypo symptoms

I am not a doctor, so I really am not able to help you with any diagnosis.  These symptoms really do not sound like diabetes symptoms to me.  It sounds like you have had all the tests, but sometimes there cna be things that are missed and there are tests that may be more sensitive than the ones you have had.  If I were you I would probably get some second opinions.  I don't know if you have seen an endocrinologist yet, but someone in that specialty could not only rule out diabetes, but they also have a great deal of knowledge about other endocrine disorders.  Good luck to you.
