 [ Symptoms ] i have fibromyalgia being treated by neurologist now bladder is achy and heavy pressure with pain [ Disease ] hi you seem to have had just one episode of such odd urinary complaints and this can occur due to some low grade partially treated urinary infection i suggest you to wait for 2 3 days and see the progress drink plenty of fluids and water high urine output may wash away all the infected material and you should be fine if at all the symptoms worsen you may go to an er thanks
