Dear Jola: A stretched bladder is due to muscle problems that is fatigued and needing some recovery. Some vitamin E, vitamin C sodium ascorbate and magnesium citrate or magnesium gluconate 250-500 mg per day may help this muscle problems related to the bladder issue. Some aloe vera juice may also help some regeneration and reduce the stretched feelings.
A sea salt, d mannose, and other supplements for urinary problem takes a while for a recovery and the pains will reduce bit by bit because of long term bladder issue is what also slows down recovery somewhat although improvement can be seen still.
