How do the symptoms compare between allergies and a cold?

The symptoms of allergies and summer colds are quite similar, often presenting as nasal congestion, runny or stuffy nose, itching and sneezing. Itchy and watery eyes are also common. However, colds typically involve a general feeling of being unwell, body aches, and sometimes a fever, which sets them apart from allergies. Allergies do not typically cause fever.

How long will the symptoms last from allergies or a cold?

A cold typically lasts around 7-10 days, sometimes extending up to two weeks, before resolving on its own. Allergies, however, can persist for weeks or even months in East Texas, depending on the duration of the season and individual sensitivity.

How can you tell if you are contagious?



It’s hard to pinpoint when you become contagious, as it typically begins a few days before the cold symptoms appear and continues throughout their duration. Contagiousness can even persist for up to two to three weeks after symptoms subside. Therefore, it’s crucial to practice good hygiene while you’re sick and afterward, and to inform close contacts about your recent illness.

When do I need to see my doctor versus take over-the-counter medications?

Many colds clear up on their own or with over-the-counter medicine. If symptoms are severe or persist beyond 7-10 days, see a doctor. For allergies, over-the-counter medicine might help. If symptoms persist or are hard to control, consult a doctor.

What are the main seasonal allergies in East Texas?

Seasonal allergens vary by season. In spring, its trees; in summer, grasses; in fall, weeds. In winter, mountain cedar pollinates. Mold levels fluctuate year-round. In East Texas, seasons can be longer than in other areas. Tree and weed seasons, typically two weeks elsewhere, can last two to three months here.
