Just got back from the doctor.
I explained everything to him, and he took my blood pressure. He said it was perfectly okay.
He said it is related to the work and stress I'm under, and he assured me he will help me get back to my training.
Since I am at the peak of the final examinations, he said there is no rush and I can go back for a full physical for xrays and whatnot to figure out what exactly is wrong.
What a relief.
