HELP! A Very uncomforable huband on my hands!?

That sounds an awful lot like Seabather's eruption. I looked this up for you. It is a rash that occurs when a swimmer is stung by marine life larvae. The condition has many names, including sea lice, pika-pika, sea poisoning, sea critters, and ocean itch.

Shortly after being stung, a swimmer may complain of skin discomfort. The rash develops in a few minutes to 12 hours after swimming. The rash consists of raised, hard or soft bumps, or blisters of different shapes and sizes that appear very red and may be extremely itchy. The larvae can become trapped in the fabric of a swimsuit, under swim caps and fins, and along the cuff edges of wet suits and T-shirts. The rash often appears in areas of the body that were covered.

Occasionally, other symptoms may occur with the rash, including nausea, vomiting, headache, fatigue, a general feeling of illness (malaise), pinkeye (conjunctivitis), and urethritis, the inflammation of the tube that carries urine from the bladder to outside of the body (urethra). Fever may occur, particularly in children.

Do not rub your skin. If larvae are on your skin, rubbing will cause them to sting. Remove your swimsuit as soon as possible. Since larvae can become trapped in the fabric of your suit, it is important to remove a contaminated suit to prevent more stings. If available, rinse your suit in household vinegar or rubbing alcohol. Wash your suit in hot, soapy water and dry it in a dryer, if possible, before you wear it again. Shower with fresh water. Apply soap and vigorously scrub your skin. Do not shower with a contaminated suit on. If larvae are trapped in the fabric of a suit, a freshwater shower will cause the larvae to sting. Take an antihistamine, such as diphenhydramine or chlorpheniramine, or apply hydrocortisone cream (1%) to help control itching. Note: Do not use the cream on children younger than age 2 unless your doctor tells you to. Do not use in the rectal or vaginal area in children younger than age 12 unless your doctor tells you to.

Use an ice pack to help relieve pain. Keep the rash clean. Wash it every day with soap and water. Hope this info helps!!

It could be a million things. It could be an allergic reaction, exposure to something like poison ivy, a jelly fish sting, sun poisoning, or an STD. He should go see a doctor to find out what it is and to get treatment, and hopefully some relief.

Maybe there was something in the water he was allergic to. Or maybe he was bitten by something. Sounds like he needs to go to the doctor. Maybe some Benadryl?
