strange itchy bumps on skin

[Benny Z]

i was in my tank moving corals around and pulling off hydroids on monday after work. was in the tank for probably 20-30 minutes or so and brushed up against all kinds of things (corals, rock, micro life). at one point i remember feeling a stinging sensation on the underside of my right forearm, but didn't think much of it.

ever since, i've had these little itchy red dots that look a rash on my forearm. any idea what this could be from???

He's only giving part of the story - he get's around you know - working at one lfs, and then another - it was bound to happen

Oh, and don't forget tank maintenance....he's "reef-easy".

BEN
Try putting vinegar on it. I had the same thing when I move some rock from Henry into my tank. Worked pretty good. Mine itched like crazy. Good Luck

thanks...i'll give that a whirl. someone else suggested calomine (sp?) lotion. i'll try both.

If the bumps are from a "sting" the vinegar can help, but usually it needs to be done very quickly. Once the toxin is in the skin the topical application success is limited. Other immediate tricks are using dilute bleach OR dilute ammonia (both denature the protein of the toxin) However DO NOT MIX BLEACH AND AMMONIA!!!

Benny, in your case, I would go with a hydrocortisone cream as that may help reduce the redness/itchyness etc. Calamine lotion might help too as it will help to dry it out.

You're going to die.

LOL :lol: I was going to say something about the Herpes too.

I agree with Brad, you are going to die. Can I have your tank?


I have had this happen to me, but not as bad as it is on you. I got some bumps on the tops of my fingers. It happened to me when I brushed up against two particular corals. One is a given, a Fire Coral of the Millipora genus. It also happens when I brush up against my Frogspawn (Euphyllia divisa). Other Euphyllia species may have the same effect, I don't know. As you know, they have some pretty powerful nematocysts.

It will itch until it goes away, and if you itch too much it will puss clear liquid. It can take quite a while to go away, especially if you keep putting your arm in the tank and if you get stung again (obviously). I don't have a time frame for you, but when I get stung it lasts at least a week. I usually keep putting my hand in the tank and keep getting stung, so it typically lasts longer than a week on me .

 

[saltyseaman]

Oh, and I've never tried any creams or anything, so I can't comment on that. I just wait until it's gone, and typically forget I even have it until one day I notice that I did have it and now it's gone.

 

[FloatingFish]

So Ben you had to " work late " last night?

Dont scratch it. You"ll make it last longer.

I used to get the same reaction every time I put my hand in the tank - even if it was not near rocks or anything. Though it is dorky, I now usually use either a latex glove or those arm-bag type gloves that go up to your armpit. They are hard to work with if you need to do delicate work b/c they don't allow for great dexterity or tactile sensitivity, but it's better than itching for days after doing any maintenance. JME.

 

[Vitaly]

Do you recall how much time passed for the rash to develop after you finished in your tank (Monday)? Is it on both arms (assuming they were both submerged) or only the one in the that was in the tank?

From the picture it appeas to be a typical Contact Dermatitis; that could have a number of causes. It should resolve itself within a week. Avoid scratching it, exposing the region to extreme temperatures, waering constricting/abrasive clothing and use hydrocortisone cream (1%) to reduce the inflammation.

If it appears to be worsening (itchier, redder, spreading over your forearm) then see your primary care for stronger treatment.

 

[medic29]

Well...hmmmm

You can use all of the above, if you do go with the Calamine lotion, do not use Caladryl, it can cause a sensitivity to benadryl. Speaking of Benadryl, you can take some of that or another antihistamine such as Claritan...obiviously use generics. The antihistamines will take the itch away. Be cautious though, benadryl will cause drousiness; if you take it during the evening you will sleep well.

I agree with Vitaly, it is contact dermatitis. I've gotten this a few times while working in my tank. Washing it with soap and water and some Benadryl and all is well.

thanks everyone! it does itch, but i'm not itching it. if i were my wife i'd have a hole dug in my arm by now. she's the picker/scrather - not i.

i noticed a red area shortly after being in the tank. it itched pretty soon thereafter and i noticed the bumps late the next evening.

it's strange - i did have both arms in the tank, but it's only on the right arm. aside from my own tank i have handled huge quantities of liverock and corals and have never had this happen before!

very rarely do i stick my hands in the display. yet another reason just to leave well enough alone! :lol:

 

[jdieck]

It could be some toxin, it could be an alergic reaction but whatever you do do not scratch it. It sent me to the hospital for four days with a nasty infection into my blood.
It could be nothing but please take it seriously, there has been new cases of vibrio infections (very life threathening) around so you want to consult with your doctor.

i seem to get the same thing when my arm rests or brushes up against the top trim on the tank. i think its from all the dried salt touching wet skin. usually itches or burns, but goes away in a day or 2.

 

[pokerfish420]

I think I saw the same thing on CSI.. I got first dibs on the first spider to climb out of his arm.. I think Ill name him Mr. Bungles or something catchy like that..

 

[pokerfish420]

I forgot to mention.. Dont be rubbing that arm on my pokerstar no matter how strong the desire to do so is.

I have had similar situations in both fresh and salt- although the symptoms are most likely the same from diffrent irritants. I also agree with the dried salt being ground into the arm when rearanging can cause this. And one must expect that the dried salt prob has some other irritants present also. My onset time for that kind of situation is usally within 20 minutes. Longest it has lasted was a couple days, but usually within hours its forgotton. I have quite sensitive skin, as well as many allergies- but also (lucky for me) a real high tolorance for being able to ignore itching and pain. Unless it is a specific sting, it will go away of its own volitian, as long as you don`t scratch and cause a secondary infection. There are many crystal like corals on live rock that will hurt, as well as bristleorms- easy to tell if that is a issue because you will see fibreglass looking threads around the wounds- unless the have been scratched away (while the tips remain).
