2) i just know wut type of acute sinusitis i have n that is ethmoid sinusitis. Its by location actually

3) i have allergic rhinitis n that's the reason why ive got sinusitis.

now a lil explanation ok..

Eczema is a form of dermatitis,[1] or inflammation of the epidermis.[2] The term eczema is broadly applied to a range of persistent skin conditions. These include dryness and recurring skin rashes which are characterized by one or more of these symptoms: redness, skin edema (swelling), itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding. Areas of temporary skin discoloration may appear and are sometimes due to healed lesions, although scarring is rare. In contrast to psoriasis, eczema is often likely to be found on the flexor aspect of joints.

Contact Dermatitis is of two types: allergic (resulting from a delayed reaction to some allergen, such as poison ivy or nickel), and irritant (resulting from direct reaction to a solvent, such as sodium lauryl sulfate, for example). Some substances act both as allergen and irritant (wet cement, for example).. About three quarters of cases of contact eczema are of the irritant type, which is the most common occupational skin disease. Contact eczema is curable provided the offending substance can be avoided, and its traces removed from one’s environment.

Irritant Contact Dermatitis is a dose-dependent reaction to chemicals commonly found in soaps, turpentine, household detergents, solvents, cleaners, and strong alkali and acidic compounds. These chemicals have a direct toxic effect on the skin. Chemicals found in soaps, shampoos, and jewelry cleaners more commonly affect the ears.

Photoallergic Dermatitis also known as photodermatosis or solar urticaria, is an inflammatory skin condition that develops when a substance (generally a drug) is altered photochemically so that it haptenates with skin or carrier proteins to form an allergen. The reaction may be elicited when a systemically ingested substance or topically applied substance is altered by blue-violet light (400-500 nm). When the etiologic agent is a topical substance, the dermatitis is considered a true delayed hypersensitivity reaction that requires prior sensitization.

Chemicals that may elicit the reaction include halogenated salicylanilides (found in soaps) and topical phenothiazines and sulfonamides (found in sunscreens). Although chemicals are generally believed to be the causative agents, some evidence suggests that airborne allergens and sunlight may trigger a similar reaction. Often, an etiologic agent cannot be determined.

I think everyone knows wut sinusitis is so there are several paired paranasal sinuses, including the frontal, ethmoid, maxillary and sphenoid sinuses.
Ethmoid Sinusitis can cause pain or pressure pain between/behind eyes, headache.

Allergic rhinitis, known as hay fever, is caused by pollens of specific seasonal plants, airborne chemicals and dust particles in people who are allergic to these substances. It is characterised by sneezing, runny nose and itching eyes.

wah so many allergies huh..
