I'm a Fish!
Is it possible to develop allergies to jellyfish venom? The reason I ask is this: I'm pretty used to getting sea lice during the summer here in florida (or swimmer's eruption, thimble jelly larvae, whatever you'd like to call it). Well I've noticed a big change in the effects it has on me.

For example in this photo: was taken in december of 2004 the only signs are little red bumps. Slight itching.

But in this photo: taken today shows what I've been experiencing the past couple weeks. Warning it's pretty gross.

It started two weeks ago: I was stung around the mouth (regulator area) chin and cheek. The day of it was like normal, I didn't use any medication (as usual) except for a natural sea salt spray with lysozyme. Which is just a natural cleanser. Pretty much exactly 24 hours later ooze was coming out of the stings. Slightly greenish. liquidy. Had to use some tissues to keep it from dripping. That healed within the week. Than this past saturday I was stung around the ankle areas. Quite a bit more pain, much more itching. Than yesterday I'm stung again in the same area, this time extending up to knees area and a little on my knuckles.

Now my legs are on FIRE. They ooze semi clear stuff. Some of them develop into bubbles like in the second pic. And some straight out explode or something and there are little chunks of skin missing.

So... is it possible to become allergic to sea lice via extended multiple exposures? Or is it possible that this isn't the typical sea thimble larvae? Did I just swim through a lot of them? Another jelly could be a siphonophore which my buddy saw on the surface. By the way, he was stung as well, but his stings look far less severe than mine even though we were probably less than 10 feet from each other.

Any ideas? I need some hydrocortisone pretty bad, gonna make the trip tomorrow morning.
 
Hi MantaRey,

No fun.

It is well known that repeated exposure to an allergen such as the protein component of thimble jelly larvae and related cnidarian venom can lead to an increase in the strength and severity of reaction. Moreover, repeated exposure can cause the spread of sensitization to allergens similar to but not exactly same as the original agent.

Cnidarian venoms can cause both toxic and immune responses. Whether the clinical picture described in this inquiry is soley or even primarily the result of a progression of sensitization is not known.

However, given that increasingly severe sensitization can lead to life-threatening reactions, it is considered prudent to have apparently progressive or extreme responses to envenomations evaluated by an allergy specialist.

This is educational only and does not constitute or imply a doctor-patient relationship. It is not medical advice with you or any other individual and should not be construed as such.

That's what I was afraid of. :-/

I'll get it checked out.
 
I know an instructor who is severely allergic to jellies, to the point of anaphylaxis. She still dives. She just covers up completely.
