Question 1

Does a CBC test show any kind of infection or overall health issues? I mainly have symptoms of laziness, and pain in my legs and back. Would a CBC test be useful in my case?

Question 2

I have noticed some solid lumps below my tongue. I went for blood tests for CBP and ESR, and the results are:
Hemoglobin: 17.8
RBC count: 5.73
Hematocrit: 49.2
MCV: 86.0
MCH: 31.1
MCHC: 36.2
RDW: 11.3
Platelets: 2.91
TLC: 6500
ESR: 6.0
My hemoglobin, RBC, MCHC, and RDW are above the expected range. Could this cause any problems? Please suggest what I should do.

Question 3

I am experiencing pain in both hands, which sometimes becomes unbearable. The pain extends from my arms to my fingers and even my palms. According to my blood tests, I do not have any infection or fever (dengue, etc.). I do not understand the reason for this pain. My hands feel very weak, and I am unable to lift or hold any weight. The pain lasts throughout the day and night, but occasionally it becomes extremely severe. What could be causing this, and what should I do?

Why is the antigen on the red blood cell not harmful?

The red blood cells will be harmless because they lack antibodies which can create any impact on the blood cells
