Lower than usual blood pressure and pre syncope?

i usually have very high blood pressure. and high heart rate. Normal for me is 100 - 120 bpm with 195/110 or higher b.p. lately i have been having mild kidney pains and My heart rate has been in the upper 50's to low 60's and My blood pressure is 100/80 and i keep having head aches and presyncope. i don't ever get head aches but ive had lots of them in the last few months. after physical activity i get cloudy urine. but only after activity. even if i stay well hydrated. not sure what that's about. My stools have also been getting less and less solid over the last few months as well. no change in diet. but i have gained wight. Dr. says i'm fine but i don't think so. what do you think? I have a family history of kidney trouble so i am concerned. 4 people in My family have had a kidney removed at some point in their lives so any kidney symptoms i have are a concern. i have seen a nephrologist. he says i have borderline low citrate levels which is the couse of the kidney stones i have every few years. but still no word on the cloudy urine after physical activity. could be as simple as walking. it hasn't been confirmed but i think i might have a little gout too. i have rheumatoid arthritis. had that since i was a teen. i thought a read somewhere that cloudy urine and gout can be connected. is that correct or am i remembering wrong? any ways i'm rambling. whats your opinion?
