respected user, hi I evaluated your query thoroughly. * Urinary incontinence is not a problem that will increase while sitting in car & normal at home . * There is something lacking at the diagnostic level. * Kindly consult with all details of symptoms , all reports done as an attachment for scanned papers , so that we can judge it & make best possible comments on the case. Thanks for using health care magic & giving me an opportunity to assist you Regards dear.
