Rash: Many people get the scabies rash. This rash causes little bumps that often form a line. The bumps can look like hives, tiny bites, knots under the skin, or pimples. Some people develop scaly patches that look like eczema.
The rash can appear anywhere, but it often starts between the fingers. The rash may then spread and turn into tiny spots. This may look red on lighter skin. The rash may leave dark spots on the skin.
Your first signs that something is wrong will be intense itching (especially at night), and a pimple-like rash. You might notice these symptoms all over your body. Or they may be limited to certain areas, like your wrist, elbows, genitals, butt, or the webbing between your fingers.
In adults and older children, scabies is most often found: Between the fingers and toes. In the armpits. Around the waist.
A doctor can often diagnose scabies by visually inspecting the rash and noting any accompanying symptoms. If a doctor still needs to confirm that the rash is scabies, they can perform skin scraping to get a sample for analysis under a microscope.
Unfortunately, in practice, scabies is largely diagnosed based only on the clinical picture, which may lead to a misdiagnosis. A broad differential diagnosis of scabies can include atopic dermatitis (AD), allergic contact dermatitis, nummular eczema, arthropod bites, dermatitis herpetiformis, etc.
Notably, scabies can live for 48-72 hours on a mattress. It is also important to note that scabies can still live for up to 72 hours or three days, even without human contact.

Symptoms and Causes
In addition to the rash, signs and symptoms of scabies include: Intense itching, which is worse at night and could make it hard to sleep. Bumps that sometimes become infected as a result of scratching. A later rash that looks grayish or skin-colored lines on the skin.
But the history of the rash can be a very important clue. If you don't usually get rashes, but you develop an itchy rash after being in a crowded living space, it might be scabies. If you've had rashes that come and go in the same areas over years, it's more likely eczema rather than scabies.
Permethrin is the drug of choice for the treatment of scabies. Topical permethrin should be administered every 2-3 days for 1-2 weeks to treat crusted scabies. Benzyl benzoate 25% (with or without tea tree oil) Benzyl benzoate may be used as an alternative topical agent to permethrin.
The most common symptoms are: Blisters or bumps — Pink, raised bumps with a clear top filled with fluid are likely to appear on areas of the body where scabies have infested. Itching — A sensation of a foreign object crawling on the skin will create constant and sometimes severe itching, especially at night.
Mite bites.
Intense itching and many small, red bumps, like pimples, are seen. Burrows may also be seen. These look like thin, wavy lines.
Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most common symptoms of scabies are intense itching and a pimple-like skin rash.
Common Symptoms
Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies. A pimple-like (papular) itchy (pruritic) “scabies rash” is also common. Itching and rash may affect much of the body or be limited to common sites such as: Between the fingers.
The most common signs and symptoms of scabies are intense itching (pruritus), especially at night, and a pimple-like (papular) itchy rash.
No. Scabies is predominately transmitted via prolonged, skin-to-skin contact with someone who has scabies.
All infested items should be decontaminated by hot washing and drying cycles. Thoroughly clean and vacuum rooms and furniture if the person has crusted scabies. If a member of a household has scabies, all persons living in the household should be treated at the same time to prevent re-infestation.
A scabies infestation causes intense itching (pruritus) which leads to scratching and damage of the skin (excoriation). If left untreated, the infestation may last for years, and has been called the seven year itch. Rash and open scratches from a scabies infection.
The scabies rash takes the form of small, red bumps that may look like pimples, bug bites, hives or knots under the skin. You might be able to see the burrow tracks created by the mites, which appear as raised lines of tiny blisters or bumps. Some people develop scaly patches that resemble eczema.
Scabies usually spreads to sexual partners and household members. Scabies can also spread through contact with the clothes, bedding, or towels of someone who has scabies. Scabies spreads quickly in crowded areas where close body and skin contact is common.
A person can also get scabies indirectly by sharing towels, sheets, blankets, pillows, or clothes with someone who has the condition. Pets and animals cannot spread scabies. Pets can get mange, which results from a different kind of mite and could make someone itch for a few days, but it is not the same as scabies.
These night biters can be mites, fleas, mosquitoes, lice, spiders, and ticks. Most of these insect bite marks look alike; hence, you should first look for bedbugs and investigate further.
Mite bites may also cause hives or welts and sometimes cause a hard bump on the skin and swelling. Sometimes, mite burrows are visibly evident under the skin; these look like small wavy lines under the surface of the skin.
