text: very urgent plx about mother's disease? she has high bp (can reach 200) and cause she to have pain in her chest she also mention that her leg is very painful after a injury recently, she feels dizzy  and said she cannot see thing as if she is very bad shortsighted. also she cannot sleep well doctors have do body check but they cannot find why her cholesterol level is normal no heart disease foud but high rbc level she had pulmonary tuberculosis in her 20's plx help if you know what would be the cause see another doctor.  they should probably do a renal ultrasound + dopplers of the renal blood vessels.  your kidneys are involved in both bp regulation (through water+salt retention) and also rbc production (through erythropoetin secretion).  damage to the kidneys and/or stenosis of the arteries could do this.  it is also possible that she has something called polycythemia vera which is a pathological overproduction of rbcs (are you by any chance, jewish?).  it can cause all of the symptoms you described except the high bp.  what else?  pheochromocytoma (adrenaline-secreting tumor).  this can be checked with a blood or urine test for metanephrines (metabolites of adrenaline).  other tumors of the adrenal glands (check aldosterone levels).  she may also have a transient cardiac arrythmia that comes, causes her symptoms, then goes away before she sees the doctor (so they wouldn't see it).  if none of these things are the case, it might be worthwhile to look at her brain with an mri or ct scan.  she probably has increased intracranial pressure, but it's hard to say whether that was caused by the high bp or is *causing* the high bp.  kind of tough to figure out what is wrong with her without seeing her in person....
