Quaddle therapy
The so-called wheal therapy has primarily nothing to do with the treatment of allergy-induced wheals. It is a method in which a certain drug is injected directly under the first layer of skin, which then swells it like a wheal. The resulting wheals are a small drug depot that can then act in the body.
Almost always, pain-relieving drugs are injected directly under the upper layer of the skin so that they can be delivered piece by piece to the painful part of the body. The wheal treatment with an analgesic is used especially for back or joint pain. The side effects of this treatment technique are minor, but can sometimes manifest themselves as local irritation of the injection site.
A disadvantage is the relatively fast degradation of the drug, which may also be associated with a recurrence of the pain. Quaddle treatment is still used today by pain therapists and orthopedic surgeons for back pain. Some family doctors also still carry out wheal therapy.
