Hello,, i have a hydrocele that is being removed in 2 weeks but recently about 2 weeks back i started having light aching pains in my lower back but not very often now they are getting worse but still not alot of pain just aching in the lower part of my back and a light sharp sensasion in my lower left side i went to the doctors because of slight burning when i pass urine and a milky substance was passed also the test results came back and they said i had a high red blood cell count (44). could someone give me any suggestions on what you might think it is?
