How Long After Eating Shellfish Can You Get Hives
Hives from head to toe an hour after eating shellfish for the first time. No swelling or breathing difficulty but extremely itchy and uncomfortable...
Likely allergic!: I highly recommend taking Benadry, two tablets, to help reduce the itching and discomfort. If you develop any facial/mouth swelling or difficulty breathing, then you have to call 911 for help. Benadryl (diphenhydramine) takes roughly 30 minutes to work. Then you need to see an allergist for testing to determine your specific food allergies. Hope this helps. ...Read more
Not very long: With food allergies hives either alone or as the first symptom of a more serious life-endangering condition called anaphylaxis typically appear within 5 minutes to 2 hours after the first bite. When appearing in a few minutes hives usually appear around the lips, eyes, face & neck. When 1st appearing after 2 hours hives can appear anywhere. Hives may be delayed as long as 8-12 hours after eating. ...Read more
Why does my face get hives after eating a certain food but other times my face will be fine when eating the same food?
No food allergy: You probably are not truly allergic to the food and it is just a coincidence. Perhaps the food in question is an innocent bystander and another food is the culprit or there is another reason that you have hives and that reason is not related to food whatsoever. We eat 4 - 6 times a day and hives may seem break out after a food by coincidence. ...Read more

I've been getting hives (1-3 small bumps) in a same spot on my tummy right after eating breakfast, a few x a week. Weird! Maybe Lactose intolerance?
NOT LACTOSE INTOL: When you have lactose intolerance, you lack the enzyme needed to digest lactose sugar. If you ingest foods with lactose, it is digested by gut germs making you gassy and often have watery acidic stools. This is not allergic and does not give hives.Recurrent hives is a single location may be a local contact agent like the nickle in a buckle, or other allergy producing trigger. ...Read more

Is anaphylaxis without hives or swelling common? Would chest pain alone after eating code as anaphylaxis in your clinical and educational experience
Uncommon, but: Anaphylaxis can still happen without hives or swollen soft tissues, can manifest as severe shortness of breath, blocked upper airway, severe hypotension, and other less common reactions. Chest pain is different, can be cardiac (e.g. coronary spasm) or esophageal spasm, its relation to eating cod can be just coincidental, and you need to make sure it isn't a cardiac problem first, good luck ...Read more

Each time my child goes to the beach if any sand touches her skin breaks out in hives, could this relate to her severe seafood allergy?
The sand itself shouldn't cause any problems but the stuff in the sand ie parts of sea critters can definitely cause problems
Allergic: This is an anaphylactic reaction and from now on you must avoid the seafood which caused the problem and carry an Epinephrine pack (2 syringes) with you in case of accidental exposure. Do note that seafood allergy is usually specific to that seafood (however shrimp allergy often means crab ; lobster allergy as well). If mixed seafood was the cause, you need to consult an allergist. ...Read more
Only after eating fish/seafood I always have a fishy smell from vagina the next day. Lasts a day or so then it goes away. Is this normal? Causes?
Not related: Vaginal discharge requires an examination to determine the cause and treatment. Bacterial vaginosis is the most common cause and often has a vaginal odor. Vaginal itching can be a sign of a yeast infection. Sometimes vaginal discharge can be a sign of a sexual transmitted infection. Testing is important to determine the treatment and keep you and your partner safe. ...Read more

How long would I have to stay away from tylenol (acetaminophen) before determining my hives r not from that? I get hives when I take it, but also on days when I don't
Acute/chronic hives: Hives vary greatly in duration, so we call hives lasting <6 wks acute, and >6 weeks chronic. It depends on the cause. A mild drug reaction may cause hives lasting only a day or two; a severe one up to 6 months. Chronic idiopathic urticaria resolves at a rate of approx 10% each month, but not every case resolves. Hives due to a known cause recur whenever re-exposure takes place. No simple answer! ...Read more
Hi I am allergic to pet dander and when in contact with it I get hives so how long will my hives last?
How can I get tested for an allergy if I can't be off prednisone long enough to have my system clear out? I recently got bronchitis. Doc put me on tessalon & an azmacort inhaler. The next day, I had hives. The next day, worse. Next day hives & swollen lips
No need: What you are describing is not necessarily an allergy. Some individuals develop hives when they acquire a viral infection. Allergy testing is of no value in this case. You can always have a rast blood test, which is inferior to the skin test, but I still do not see the need for it in your case. The hives should subside once the infection resolves. ...Read more

I have been eating seafood for a long time, but reasonly I found out that I am allergic to anchovies. Is there a way to get rid of this completely?
Unfortunately, no: It's not uncommon to develop allergies to seafood as an adult. Usually, when allergic to one fish, you'll react to many other fish. However, allergies to fish (tuna, cod, salmon, etc.) do not cross react with shellfish or mollusks (crab, lobster, oysters, etc.), but you can be allergic to both. At this time, avoiding the food is the only way to prevent symptoms. See an allergist for more info. ...Read more
