How do you treat hypersensitivity to sound?

How do you treat hypersensitivity to sound?

Sound hypersentivity: Too broad question. Cause of sensitivity? Treat the cause! Trauma psychological or physical can trigger hyper response to stimuli, even though sound might not have been part of the trauma. Part of hyperarousal, state of hyper stimulation, easily startled...Treat the cause. If cause not found or not remembered (child trauma-abuses), specialists can still help find cause by different modalities.

Why can some people be hypersensitive to pain?

Why can some people be hypersensitive to pain?

Pain.: Pain is a complex psychoocial and physical process that has genetic and racial influences. Certain cultures reports more pain to stimuli than others. Early learning plays a role (modeling). In addition after a lot of pain the nervous system can become sensitized to the pain and either increase or decrease the response to it.

What is the treatment for hypersensitivity pneumonitis?

Depends: Number one is removal of the precipitating allergen (cause of the hypersensitivity). Then, depending upon the severity, short courses of anti-inflammatory meds which may include steroids may be helpful. Supportive care may include other factors depending upon the cause and the degree of impairment.

How can I cure my hypersensitivity to insect bites?

How can I cure my hypersensitivity to insect bites?

Desensitization: Allergen desensitization does not work on all allergies--it is most effective with seasonal allergens, indoor allergens and insect bites. Insect bites from bees, red ants and wasps are treated with allergen desensitization. Allergen desensitization uses small amounts of the allergen the person is allergic to and injects the allergen into the individual's body.

Had Xanax (alprazolam) first time 2 weeks ago.. 5 or 1.0 every few days. After 3 days of no pill, feel awful flushed worse than before I ever took it. Inter dose withdrawal? Am I hypersensitive to it? Taper off?

Had Xanax (alprazolam) first time 2 weeks ago.. 5 or 1.0 every few days. After 3 days of no pill, feel awful flushed worse than before I ever took it. Inter dose withdrawal? Am I hypersensitive to it? Taper off?

Hard to say: Why was xanax (alprazolam) prescribed in the first place? It generally would take longer and more consistent dosing than you describe here, for habituation to develop. You may be very sensitive to it, but this would still not habituate you sooner. More likely that the basic anxiety you might have been having, is so far insufficiently treated. Please discuss with your own physician.

What may happen in the body that triggers late onset allergies?

More symptoms: Many allergic reactions are biphasic meaning that immediate symptoms that resolve after a few hours are followed 6-10 hours later by the reappearance of symptoms without additional exposure to the allergic trigger. The symptoms are the same but may be more intense & last longer in the late phase. Prompt early treatment with topical corticosteroids usually prevent late onset symptoms.

Have keflex allergy...Any other antibiotics I need to avoid?

Cephalosporins: You should avoid all cephalosporin antibiotics ie. Vantin, Ceftin, (cefuroxime) Suprax, Rocephin, Ancef, Fortaz, Cefepime etc. There is a low risk of cross allergenicity with penicillin antibiotics. If you had immediate hypersensitivity- hives, anaphylaxis or laryngeal edema, avoid penicillin class drugs.

My dad is deathly allergic to bees and wasps but I've never been stung by either. If don't want to find out the hard way. Also are allergies genetic? Could I be deathly allergic to bee stings too?

My dad is deathly allergic to bees and wasps but I've never been stung by either. If don't want to find out the hard way. Also are allergies genetic? Could I be deathly allergic to bee stings too?

Possibly: Severe allergy to a single thing such as bee stings is not necessarily familial/genetic, but certain families DO have the tendency to be hypersensitive to things (leading to asthma, allergies and eczema). Blood tests are available to see if you also have this tendency towards severe reactions. Ask you doctor about testing for hymenoptera allergies, to be on the safe side.

Child with severe asthma and allergies. Is it hereditary?

Child with severe asthma and allergies. Is it hereditary?

Probable: Asthma is often hereditary as are allergies. However whether a disease condition will develop or not is dependent on how the body interacts with the environment. For example, in identical twins there is a close to 60% that the other twin would develop asthma if one of the twin has it. In non-identical twins, the chance is slightly under 30%.

Are allergies inherited?

Are allergies inherited?

Yes.: Yes, we do see allergies in families. Your risk of allergies increases if one parent has allergies, and is even higher if both parents suffer from allergies. Interestingly, we are seeing that exposure to allergens may also play a part in the development of allergies in children. Rural areas, with high levels of plant and animal allergens, actually have lower levels of allergic disease in kids.

What is the difference between type I hypersensitivity and type ii?

What is the difference between type I hypersensitivity and type ii?

Big difference: Type 1 is mediated by the IgE antibody and responsible for anaphylaxis, hay fever, allerg etc. Allergy skin test can identify these. Type 2 is mediated by IgG or IgM antibody and complement proteins that are "cytotoxic" that ends up killing the target cell. Examples of this are hemolytic anemia, Graves disease, Myasthenia gravis, Rheumatic heart disease, etc. For anemia, a Coombs test is used
