High RBC Count and joint pain. Advise.

I have a sebaceous cyst on my shoulder and having pain in almost all of my joints. In my blood test, RBC Count (5.86) and urine PH (6.5)is high and MCV(82.7) is low. My pulse rate is around 90 to 92.  I am also facing problem during writing. My hand is shaking. After writing 5 minutes, I am feeling pain in my hand. Almost all time I having pain in my hand. I consulted many doctors for these problems like neurologist, ortho and medicine doctor. Each doctor overlooks RBC count because it was at border line. It increasing from 2014. Upto 2013 RBC count was normal. It may be a cause of joint pain. My uric acid is normal and I dont have authoritise according to ortho doctor. I am going for cyst removal in next 6 days. Cyst may be a one of the reason. My other reports are as follows. Kindly advise.
