Hi,
Dark urine in a diagnosed case of
IgA nephropathy indicates gross hematurea (blood leaking in urine). This can happen episodically, especially following minor febrile illnesses like
upper respiratory infection or
gastroenteritis.
This condition is treated with drugs reducing protein leakage in urine (like ramipril you are already taking), and closely monitoring and treating
hypertension if any. When there is progressive increase in protein leakage or worsening renal function despite this, we need to go for other drugs like
corticosteroids or immuno modulatory drugs.
Tonsillitis (usually associated with fever / throat pain), if diagnosed, you can complete the antibiotic course- penicillin antibiotics usually will not cause kidney damage. But analgesics other than paracetamol are better avoided. Also restrict salt intake, processed food items, and include omega 3 fatty acids (like fish oil) in diet, as it is known to slow down progression of disease.
Hope I have answered your question. Let me know if I can assist you further.
