warnings and cautions
5. WARNINGS AND PRECAUTIONS 5.1. Muscle pain requires differential diagnosis for segmental nerve pain, plantar fasciitis, tendinitis, tendinosis, deep blood accumulation/hematoma. 5.2. Skin cleansing/disinfection is required before application. Saprophytic bacteria may produce injection site abscesses with improper skin preparation. 5.3. In rare cases patients may experience hypersalivation within one hour of treatment. Discontinue treatment. The hypersalivation resolves over several hours without further medical treatment. 5.4. Patients with known sensitivity to procaine or other local anesthetics should be kept under observation during the therapy.
6. ADVERSE REACTIONS 6.1 The most common mild adverse reaction is slight reddening at the injection site due to the mechanical effect of the needle or a superficial skin reaction of mild erythema.
