Water urticaria, also known as aquagenic urticaria and aquagenous urticaria, is an extremely rare form of physical urticaria. It is sometimes described as an allergy. In affected persons, water on the skin causes hives to appear within 15 minutes and last for up to two hours. Water contact can cause aquagenic urticaria, presumably due to chlorine or some other trace chemical in the water, hence you don't exhibit reactions to distilled water.
It is defined as urticaria that persists for longer than 6 weeks. In most of the cases of chronic urticaria, the underlying pathology is idiopathic i.e. it is not linked to any cause. It is essential to rule out the presence of serious illnesses of which recurring hives can be a symptom. Examples are hepatitis, hyperthyroidism, lymphomas, collagen vascular diseases, and cancers of the rectum, kidneys and gastrointestinal tract.
You could stop the medications in consultation with your doctor , but do keep some antihistamine medications at hand for use in case of a sudden flare up of symptoms.

Next time when itching start take an antihistamine pill (like Benadryl). If this will help you, it means you have physical urticaria (allergy to heat in your case).
Hello,
It can be due to cold urticaria. Cold urticaria is diagnosed by holding an ice cube against the skin of the forearm for 1 to 5 minutes. A distinct hive should develop if a patient has cold urticaria.
Patients with cold urticaria should learn to protect themselves from a rapid drop in body temperature.Antihistaminics like Claritin and zyrtec can also be taken. The antihistamine cyproheptadine (Periactin) has been found to be a useful treatment also.

An antihistamine like cetizine 1 at bedtime for a week would be of great help.It may cause some sedation.External application of calamine is fine.
acute and chronic(when hives persist for more than 6 weeks). The most likely triggers for acute urticaria are allergies to pets, horses, latex and foods, such as shellfish and nuts,bee or wasp stings,allergies to medicines,Viral infections, such as glandular fever and herpes, dental and sinus infections, fungal infections, blood transfusions and vaccines.
The cause of chronic urticaria is often more difficult to identify.
The mainstay of treatment of hives is antihistamine which may be necessary for prolonged periods (in excess of 6 weeks). Double conventional doses of these non-sedating antihistamines such as Cetirizine, Loratadine, Acrivastine and Fexofenadine may be needed to get symptom relief. Sedating antihistamines such as Chlorphenamine or Hydroxyzine are used at night to get urticaria control.
Mostly thee are urticarial rashes and you may need a sedating antihistamine like cyproheptadine.Do consult your do.
Take non sedating antihistamines like Claritin or Zyrtec to get symptom relief. Sedating antihistamine such as Benadryl is used at night to get urticaria control. Short courses of oral cortisone or steroids are taken for short periods (one to three days) to settle more severe symptoms.Also apply calamine on the rashes.
You may take Vitamin C along with the prescribed treatment. Vitamin C is a general anti-allergy supplement.
Hi. I have hives(urticaria) almost everyday for 12 weeks or so. I've seen 2 dermatologists. I've been on xyzal,doxepine and hydroxyzine with little or any real benefit. The hives are red and itch. They come and go. Other than that I have no other problems. My doc said they usually never find a reason and most go away over time. No blood tests ordered. Anyone have any suggestions? It's annoying.

t sleep, and the hives were really bad this morning, so we went to the hospital, where they gave her an IV with antihistamine and cortisone. The Dr. prescribed two type of antihistamines, loratadine and dexchlorpheniramine, as well as a once daily steroid prednisolone. A couple hours after returning from the hospital, the hives worsened. They are spreading across her body and the itching in unbearable. Solarcaine, aloe, cool baths, etc. have little effect.
I went to the doctor and he diagnosed me with dpu or delayed pressure urticaria... basically any pressure applied to my skin cases a hive break out so standing, walking even using my hands are causing issues... the doctor signed me out of work... I am 9 weeks pregnant and can't take any antihistamine in the 1st trimester and he can't guarantee it will work to reduce symptoms either...
I was siagnosed about a year ago. It has been the worst diagnoses along with my death sentence of MRSA Staph infection. I thought it was a string of bad luck for me but bad luck shouldn't last my whole life or at least to what I have left. I'm on medications for this chronic urticaria. the following is Doxepin 25mg, Rantidine, and my epi pen. My doctors described this as something related to my staph infection or stress.
