I am 42 years old male, weighing about 80 kg and 5'6" tall. The skin of my scrotum and penis is itchy and inflamed. The skin in my penis has burning sensation as well. I am not sure if this came about after my contact with my wife and/or after eating shrimps. I say after eating shrimps because I remember two years ago after eating shrimp my scrotum had the same symptoms but at that time my penis was not affected but my armpits was as inflamed and itchy as my scrotum. What do you think is the cause of this and how can it me treated? Thanks
