Scorpion, spider or tick bite

Arachnid bites, in general, produce mild discomfort in the case of non-poisonous spiders. In contrast, the scorpion, which also lives in desert areas in humid areas of Spain, is more dangerous. This arachnid will only attack if it feels threatened or bothered because it has a very developed sense of self-protection.

It is usually small and does not reach 15cm, but in its articulated abdomen there are small deposits that contain poison and that it inoculates through a sting at the end of its tail. It is a very strong and resistant animal, adapting to any extreme climate.

Their venom varies according to the species, although they usually give local reaction or temporary discomfort. In some countries, its poison can be deadly or it can also cause serious complications in babies and children.

They usually bite on hands and feet as a response to some reaction (for them aggression) on our part. The first thing we notice will be a strong pain, swelling and redness of the area. This is general for scorpions, spiders and ticks.

Prevention and Treatment
To prevent a scorpion sting, one of the best known recommendations is not to move or lift stones of medium or large size because the arachnid can be underneath. In areas where the presence of scorpions is common, then before putting on our clothes and getting dressed, we have to shake it, as well as turn the shoes over to make sure it is not inside.

If we end up biting, the first thing we should do is:

Clean the wound.
Disinfect the wound.
Place ice covered with a handkerchief or cold compresses on top.
The affected limb will remain at rest (the person also).
Observe any change in the area.
Go to the nearest medical service.
For the case of spiders, we are only going to consider the most dangerous species indicating in which country or region it is as an orientation method for prevention since its treatment is practically the same as that of snakebites:

Atrax Robustus – Australia (east coast)
Latrodectus tredecimguttatus or Black Widow – Europe (Spain included) – Asia
Latrodectus hasselti – Australia
Latrodectus mactans – Argentina, Chile, Mexico and El Salvador (inhabits in America generally)
Loxosceles laeta – South America, Central America, Finland and Australia
Loxosceles reclusa – America in general
Phoneutria nigriventer – Brazil, Argentina and Uruguay
Phoneutria phera – Peru and Brazil
Sicariidae – World distribution
Theridiidae – World distribution

Ticks are also arachnids (hematopod arthropods), although smaller than scorpions. Its basic food is obtained from the blood of mammals including man. Unlike insects, they do not perform a temporary sting but remain on the skin of the animal they parasitize. The most dangerous from the health point of view, is that in addition to sucking blood pierce layers of skin and introduce part of his body nailed to continue sucking continuously, which causes risk of infection and parasitic transmission.

They usually appear in the spring months (late April and May) and the larvae inhabit the growing grass, waiting to get hooked on some animal. If we detect that a tick has bitten us, the most normal thing is that it is alive and hooked to our skin in armpits, groin or hair that are hot and humid areas.

To start it, it is convenient that before it is dead. Usually insecticide-type products are used or even drowning in oil. Then, by means of tweezers, the part where the head is inserted is held tightly and stretched in a single block so that it does not break. Immediately, the wound is cleaned and disinfected. So this is the summary for:

Treatment of the tick bite:
Removal of the tick by pulling with fine forceps (avoid the use of fingers or a tissue)
If you split, and there is the head or chapter where the salivary glands are located, that area should be removed with a scalpel so that in the future there is the possibility that it causes neurotoxic paralysis.
Administration of antibiotic (the most commonly used is doxycycline since it is the first treatment for Lyme Disease and botoneous fever).

Medical exam
The medical examination will depend on several factors such as:

Endemic zone (existence of certain types of tick species that are vectors of bacteria or viruses that predominate in the area)
Initial symptomatology (febrile processes, general state of the patient, …)
Discard other types of bites
Initial state of the person (if he had any pathology, he was taking medication, …)
For example, in the United States and other areas of the American continent we can find the Rocky Mountain fever produced by the bite of ticks that transmit a bacterium, the Rickettsia rickettsii.The incubation period is 3 to 15 days and comes with:

Shaking chills
Muscle pain
Sensitivity of the eyes to light
Mental confusion

On the 6th day of incubation, a general eruption appears that reddens the skin, overlying the palms of the hands and feet that constitute small hemorrhages. The person should be treated immediately since the infection is serious and may cause death.
The treatment recommended in the literature is varied, although antibiotics or chloramphenicol are usually administered during the febrile process.
