Greetings from healthcaremagic.com.
I an Dr Sourav Chakraborty and i will be helping you with your query .
I have gone through your case scenario in detail and i do believe that your symptoms need further evaluation . As you mentioned lupus
and poly cystic kidney
disease runs in your family i suggest you to get an ultrasonographic evaluation done to see your kidneys . Anemia
along with other causes can give to swelling in face and body so please do get your haemoglobin
level checked at the earliest. Foul smelling urine could be attributed to urinary tract infection
and can be controlled with proper antibiotic coverage . Please visit your doctor for further information . Hope i have been able to help .
Take Care .
