The girls were walking for four hours today, but rain and wind didn't stop them. They went shopping. Tell me when they arrive home, sharp pains in the crotch started to appear and cut very painfully. Now when I move or just walk, it hurts badly, even when turning over, this pain is felt in the crotch very sharply cuts, even when turning over. Is it dangerous?
