Yes. It is possible as I am living proof. After a car accident in December of 2014, my pain Doc ordered an MRI on my brain to rule out head injury for the headaches (I took two air bags to the head). Those results came back normal, with the exception of some white spots on my frontal lobe, which my PCP told me not to worry about. I won't get into the years of symptoms and the psychiatric therapy I'd put myself in because my PCP had convinced even me that it was all due to Anxiety. Two weeks ago, I was in the ER and a CT scan incidentally located a tumor in my brain. The following week, I underwent another brain MRI - this time with and without contrast. This MRI confirmed the mass, which they believe is a benign meningioma. I was concerned about the size because I believed this thing must have been less than 3 years old, only to learn that the Radiologist compared this MRI to the 2014 MRI, and claimed it WAS there back then and looked "unchanged". So, yes . . . it is possible. I have so many mixed feelings about the years of confusion and misdiagnoses (I was also misdiagnosed with Glaucoma this past October as my Optomotrist had no explanation for the stark decrease in my vision). But I'm glad to finally know that I wasn't crazy. My symptoms were real, and now I know why. Hope you ride your GP better than I did my PCP. But it does happen - at least it did to me.
Sounds to me a lot like anxiety. Seek treatment for that and if the symptoms don't go away, work from there.
Did someone give you that impression that they were nerve related? I think you should get re-tested to make sure it wasn't a lab error.
Red blood cells, hemoglobin and hematocrit can naturally be a little higher in men than women. High altitudes can cause high hemoglobin and hematocrit- do you live in one?
There are at least a couple of meds that can increase hemoglobin and red blood cells- methyldopa and gentamicin- are you taking either of these?
Also, have you had a transfusion, hemorrhage or burn lately, because that can cause a difference? During and right after hemorrhage, both hemoglobin and hematocrit can be elevated. Had any bleeding lately that you know of?
I have an old book I'm getting my info from, A Manual of Laboratory Diagnostic Tests 2nd Edition by Fischbach.
It says hematocrit increases can be found in erythrocytosis, polycythemia, severe dehydration and shock, "when the hemoconcentration rises considerably".
It says high hemoglobin is "found in" "hemoconcentration of the blood (any condition such as polycythemia and severe burns in which the number of circlating erythrocytes rises above normal)", "chronic obstructive pulmonary disease" (COPD), and "congestive heart failure".
Increased values in red blood cells, my book says, can be caused by "extreme exercise and excitement". And it says "counts obtained under these conditions are of doubtful clinical value."
But it also says increased values can be caused by:
"1. Polycythemia vera
2. Secondary polycythemia (seen in erythropoietin-secreting tumors, in renal disorders such as hypernephroma and renal cysts, and in cancer of the liver)
3. Severe diarrhea
4. Dehydration
5. Acute poisoning
6. Pulmonary fibrosis
7. During and immediately following hemorrhage"
My h&h and red blood cells were slightly above normal. I was under the impression they were nerve related as well. I am scheduled for a nerve conduction test. I'll let you know how everything goes. Thanks for your help. I truly appreciate it.
Were your H&H and RBCs high or low in their abnormality?
The only tumors I know that can be missed are pituitary tumors - they need to be done a certain way which is called dynamic. Your symptoms frankly, and I am not a doctor, sound more nerve related or more auto-immune. That is not going to show up on an MRI and it requires testing like EMG and the like for the nerves and special tests for auto-immune. Have you ever seen a rheumatologist?
For the nerves, only certain neuros specialize in the testing. Not all of them can do it. Make sure you get copies of everything (which is sounds like you do already) and take someone with you to the appointment to tell the doctor - sometimes when it comes from someone else, they listen more - which is silly, but it sad but true.
Those are just ideas. I do not know. I just have been through a wringer myself.
