When muscle strains occur, local ointments are generally chosen for their anti-inflammatory, pain-relieving and blood-stasis-activating properties. Most muscle strains are caused by excessive stretching or sharp contraction of muscle tissue during exercise. First of all, rest is needed to avoid the recurrence of similar activities. Avoid local medication for 24 hours after the strain to prevent aggravation of local muscle tissue bleeding. 24 hours later, local capillary bleeding basically stops, and local creams can be applied to promote the dissipation of local blood stasis, which helps reduce local edema and promote repair. For example, blood pain relief ointment, Yunnan Baiyao ointment, dog skin ointment, fluoridiprophylline babu ointment, musk tiger bone ointment, etc. If an allergic reaction occurs to the skin after local application of the cream, stop using it. For more serious muscle strains, more pronounced local swelling and severe pain, you need to take oral medication at the same time for treatment.
