mild hypercalcemia, kinda concerned

I'm a 28 year old male in good shape and health. I had initially gone to my doctor for heart palpitations and mild chest pains which were probably a result of stress/anxiety. My blood test came back with elevated proteins and calcium as well, so he ordered an electrophoresis. That came back showing a mild increase in my alpha-2 globulins, and that my other proteins were within a normal range. Also, my a/g ratio was low (1.0) He sent me to a hematologist and now i'm awaiting the results of tests that will look deeper into my immunoglobulins.

I'm basically asymptomatic as of right now. With the exception of a mild cough and the occasional slight chest pain for over a month now. (never smoked)

If anyone can offer any kind of insight it would be greatly appreciated. Thank you!
