Painful rashes should quickly be evaluated by a physician. The rash is infected. If you have an itchy rash and you scratch it, it may become infected. Signs of an infected rash are yellow or green fluid, swelling, crusting, pain, and warmth in the area of the rash, or a red streak coming from the rash.

Home treatment doesn't help or the itch lasts more than a couple of weeks. The itch comes on suddenly and is all over your body. You could have an allergic reaction or an illness like thyroid problems or liver disease. You also have a fever or feel tired.
Itchy bumps can appear as a result of allergies, infections, insects, and, sometimes, nonidentified factors. However, there is one general principle that the American College of Allergy, Asthma & Immunology recommend people to follow when their skin itches: Do not scratch it.
Does skin cancer itch? While skin cancers are often asymptomatic, meaning they don't show symptoms, they can be itchy. For instance, basal cell skin cancer can appear as a raised reddish patch that itches, and melanoma can take the form of itchy dark spots or moles.
It may start to bleed in the center, where an indentation may form. In other areas of the body, BCC may appear as a small, scaly, pink patch or a pigmented, shiny bump. It may even present as an irregular scar. As the cancer progresses, the area may become crusty and start to bleed or ooze.
Bug bites may resemble hives in looks, but hives tend to behave differently. Hives may change shape and move around the body, whereas a bug bite stays in the same place. (3) Rosacea usually appears as redness on the face where swollen blood vessels become visible.
What causes hives? An allergic reaction usually triggers hives, but they can also be caused by other situations such as stress, anxiety, or exercise. Hives are a reaction to the release of mast cells into the bloodstream, which unleashes the chemical histamine.
Stress rashes often appear as raised red bumps called hives. They can affect any part of the body, but often a stress rash is on the face, neck, chest or arms. Hives may range from tiny dots to large welts and may form in clusters. They may be itchy or cause a burning or tingling sensation.
A stress rash usually looks like raised red bumps or hives that range from a single welt to a cluster of tiny dots. Commonly, these clusters will appear on the face, neck, chest, arms, and hands. However, they are not limited to those areas and can ultimately appear anywhere on the body.
What do stress hives look like? Stress hives can look a little like bug bites: both are red, puffy, and itchy, and may appear initially as individual bumps, says Stevenson. However, hives are more often irregular in shape and can join together in larger patches, especially if you scratch them.
Autoimmune rashes can look like scaly red patches, purplish bumps, or more. The appearance of autoimmune rashes will be different, depending on which autoimmune condition is triggering the skin rash. For example, cutaneous lupus may cause a scaly red patch that does not hurt or itch.
The association of malignant tumor and chronic urticaria remains controversial. Several cases of malignant tumors have been reported in association with urticaria, including leukemias and lymphomas,17,18 myeloma,19 testicular cancer,20 ovarian carcinoma,21 lung cancer,22 colon cancer,23 and thyroid carcinoma.
If a person has hives, they have a risk of developing a life threatening condition called anaphylaxis. Being aware of other symptoms of this condition, such as swelling of the face, tongue, or throat, a rapid heartbeat, or lightheadedness is important.
Some people get hives when they develop an infection like strep throat, a urinary tract infection, or COVID-19. Others get hives when they have a medical treatment like radiation therapy or a blood transfusion.
Allergic Reaction to Bed Sheets Explained
The main causes of allergic reactions from bed sheets are dust mites and mold, which live in almost every bed. Dust mites in particular are just a fact of life, living off discarded skin cells, which form common house dust.
Bedbug bites may initially look like hives with small central bumps or bites. However, hives from bedbug bites don't stay in the same place for more than 24 hours. They tend to migrate to other locations or go away.
small red bumps or welts in a zigzag pattern or a line. small red bumps surrounded by blisters or hives. papular eruptions or areas of skin with raised or flat patches that may be inflamed. small spots of blood from bites often dried or stained onto sheets or bed clothing.
What is mycosis fungoides? Mycosis fungoides is a type of lymphoma—the most common form of blood cancer. When someone has mycosis fungoides, malignant cells in the blood travel to the skin. The most common mycosis fungoides symptoms causes lesions that appear as a scaly, itchy rash.
When a rash caused by skin lymphoma (also referred to as cutaneous lymphoma) is in its early stages, it often presents as small patches of dry, red skin on the torso, buttocks or another area of the body. At this stage, the rash often resembles dermatitis, eczema or psoriasis.
Cancer treatment—including chemotherapy, targeted therapy, and immunotherapy—can cause skin issues in people with leukemia. Per the American Cancer Society (ACS), the rashes can appear across multiple areas of the body (e.g., scalp, neck, upper body) and may be itchy, burning, stinging, or painful.
An itchy rash. Leathery patches that are darker than usual (hyperpigmented), typically on brown or Black skin. Dry, cracked, scaly skin, typically on white skin. Bumps and blisters, sometimes with oozing and crusting.
