Frequent urination in small amounts.

I was diagnosed with white coat hypertension and anxiety in june 2017 . So, i am taking vinicor d 25 tabs daily. Few months back i had a blood test and my rbc was elevated . Doctor advised me to take aspirin 150 daily and after a few days of taking aspirin , i had phlebetomy . After that aspirin was reduced to 75 mg . I was diagnosed with vit d deficiency and so doctor put me on lupi d3 mouth melt granules to be taken once in every 7 days . I am not taking aspirin now . From past 8 days , i have problem of frequent urination during the daytime . I don't wake up at night to urinate. My uric acid is 8.8 . I had done blood sugar test before 3 months and it was normal. I urinate in small amounts but just after urinating i feel like urinating once again and there is a buring sensation in the urethra . However , i can hold the urge to urinate for 3 -4 hours but soon after urinating i feel like going to toilet once again . My urine is clear and has no unusual smell . Plz. Help .
