My son has spot on adrenal for a few years. Over past years has gained lots of weight, kidney stones, lots of problems with pain in coccyx and has developed arthritis in spine. Has over past few years become forgetful, periods of what seems paranoid and easily agitated. He had maximum injections to spine over past year with last one about 3 or 4 months ago and no relief of pain. A recent  scan showed some growth of spot on adrenal gland. A few days ago he had the low dose dexamethasone blood test. He is told the test came back in normal limits. My question is could the injections he had to back have effect on the blood test?
HI, Thank for choosing Chat Doctor, the way you have asked required detail clinical history along with the treatment given, your main concern is the injection he has been given, but until and unless I could know the name of injection I will not be able to say anything, the same would be applicable to your other concerns, so please send the complete clinical detail, be in touch with Chat Doctor, bye.
