She seems to have cystitis symptoms.(frequent visits to loo with not much coming out;stinging when it does;can't do a "poo";no temperature;no pains-although said her "sides feel like they're sunburned" last night!).Is this normal? She had blood in her urine once last year and that was cleared up with antibiotics-blood was pure red that time. This time,Doc says there's no blood but there's "nitrites and white blood cells and very strong".Worried sick.
