Hives

What is Hives?

Urticaria (from the Latin urtica, "nettle" from urere, "to burn"), commonly referred to as hives, is a kind of skin rash notable for pale red, raised, itchy bumps. Hives may cause a burning or stinging sensation. They are frequently caused by allergic reactions; however, there are many nonallergic causes. Most cases of hives lasting less than six weeks (acute urticaria) are the result of an allergic trigger. Chronic urticaria (hives lasting longer than six weeks) is rarely due to an allergy.

The majority of chronic hives cases have an unknown (idiopathic) cause. In perhaps as many as 30–40% of patients with chronic idiopathic urticaria, it is caused by an autoimmune reaction.

My 3-year-old son has been waking up with hives occasionally for over 5 months now. We've taken him to an allergist as well as regular visits to his pediatrician. No cause has been determined, but in doing his blood work, his AST liver enzyme continues to come back as slightly elevated. It has been at 73, 62 and lastly 63. The pediatrician has advised us to wait 6 to 9 months to repeat the test and see if the AST enzyme is back in range. Waiting that long makes me nervous and I'm looking for some reassurance that this is not reasons to persue the situation immediately. Also, is more likely that the hives are a cause or reaction to what is contributing to the elevated liver enzyme? Thank you for your time.

I have been breaking out in chronic hives for about 3 months. I have been tested for environmental allergies but no food ones. One episode this weekend was particularly bad and landed me in the ER. I am a 28 year old female. I read that chronic hives is an inidicator of liver or kidney disease. Is this likely in my case?

On Thursday, March 27, I am 58. I started having symptoms of chronic hives and swelling at 17. I was diagnos with beginning stage of Lupus on my blood test. My Doctir would give me a Lupus test each year for the last 3 years. This is the first time the test was positive. Does Lupus entail symptoms of imbalance in walking and dizzyness. I have been getting up very dizzy and walking imbalanced to get to the bathroom. It is a strain on my eyes to read or think when use the computer. Also I have been experiencing for over 40 years symptoms of chronic hives and swelling. I can't sit in air condition room or under a fan, outside in cold weather which affects my body with chronic hives, swelling, and pain my all my joints. After chronic swelling my body is very weak for several days and I'm in bed to recover my strength. I also get very sick with colds throughout my body and have to stay home in bed for several days, even when I get the flu shot. I have been treated with chronic allergy with benedryl, Claritin, zantex, epic pen, and prednisone over 40 years. At this time I'm not taking prednisone. It gives me very strong side effects, but it is the medicine that works well to keep swelling and hives in control. My Doctor said that one of the antibodies in test show positive for Lupus. He wants me to start using Plaquenil 200mg. 1 tab PO BID. Please clarify for me. Thank you, May Brown

doctor1 MD

Dear May brown , can you please send me that report , all the symptoms that you are saying can be found in lupus but I need to see that test and its titre of positivity . If you are positive for the same , you will need plaquenil.

Hello doctor, My name is Shiva Kumar . I am felling little difficulty in swallowing saliva and strongly feeling something in my throat. I m feeling, my throat is dry and little bit of blood came from my throat. I am getting hives since 5 months. Previously doctors did blood work and found nothing.

Four days back I went to dermatologist , She ordered thyroid antibody tests and found TSH=4.76(normal range: 0.358-3.74mlU/ml ),T3 Uptake=29(normal range 30-39%). They also did sonogram on heart and thyroid.They are waiting for the results. So can you tell me what could be the reason for these problems . Waiting for your reply....

Hello, I suffered from chronic hives for 71/2 years. I would have multiple outbreaks each year that only subsided after several weeks of prednisone (as much as 60 mg with a taper). i also was on multiple antihistamines to include: fexofenadine montelukast, doxepin, cetirizine and ranitidine. For the last 3 years I was finally hive free but was taking cetirizine BID and had occasional itching episodes but no hives. This past Fall I was diagnosed with osteoporosis after an arm fracture. I started on alendrolate 70mg/week in late Nov. In late January I started with a hive outbreak. I started with all the usual meds as well as prednisone. I did a taper and was down to 10mg/day but each time I tried to stop, I would have more hives. Finally after being on the prednisone for 6 weeks, at my ENT doctors recommendation I stopped it anyway. So now I have been waking up most days with hives, some days just a few, others with many. I am extremely frustrated. Hives won t kill you but they do make you miserable. The only things that have changed since Nov. were a thyroid medication dose adjustment and initiation of alendrolate. an the alendrolate be the cause of this outbreak? Are there any alternatives to the alendrolate that would not have the same result?

My son had surgery for a deviated septum on Aug. 4th, 2010. He had an allergic reaction to dilaudid and morphine (hives). Since his surgery he has developed hypertension and is only 17 years old. I can think of nothing else to cause this other than one or both of the drugs he was given. Could this be the likely cause?
