For the past year and a half my blood work has indicated slightly high calcium and low D, slightly anemic, slightly high sugar. now they vary in combination. I have been identified with reduced kidney function and this week high Parathyroid. I have extreme body spasms on the left side of neck, stomach area, back, hands and feet, and legs, bad memory, fatigue, depression,heart trouble ( 1 blockage) and just diagnosed with asleep apnea.I have had asthma all my life. Can you have a tumor on the Parathyroid gland with only slight rises in these blood levels?
