Depends: Crab allergy is a shellfish allergy and can develop at any time during adulthood. Why some adults can consume crabs their entire life without any problems and others can go on to develop symptoms is unknown. Shellfish allergy is a common adult allergen and symptoms can vary from one accidental exposure to the next so avoidance once symptoms develop is the best way to manage.

Can forced air heaters trigger allergies?

Dr. Bert Mandelbaum

Yes: Many people who have allergies are allergic to house dust. Running the forced hot air can circulate this in the house. Using a good filter in the heating system and using an air purifier in the child's room might help reduce some of the exposure.

What are so-called cross allergies?

Cross reactive?: I think what you are asking is what are so-called cross-reactive allergies. Plants in similar families can show cross reactivtiy. This is true of trees such as cottonwood, aspen, and poplar. Many of the so-called "northern pasture grasses" (grasses found in north america) also show cross reactivity - that is, if you are allergic to one species, you are probably allergic to other related species.

Reaction to HIV meds: http://en.wikipedia.org/wiki/management_of_hiv/aids#adverse_effects "allergy" is probably not the best word to use when describing reactions to medications. There are lots of side effects that are typical and common with medications for hiv. They are catalogued in the article above. Sometimes true allergies to these meds do occur. Best to google the individual medication to learn about its issues.

Possibly: Allergic reactions to food usually result in hives, itching, breathing problems, throat swelling or GI symptoms but could include headache. Some foods commonly trigger headaches in migraine suffered such as chocolate or aged cheese. These are not true food allergies.
