Study: NCT04704297

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: Treatment of Myofascial Pain Syndrome in the low back. This intervention will be based on outcomes of the medications listed below.
Description: We are testing which of the three arms is superior for the treatment of Myofascial Pain Syndrome of the Low Back. Pain will be measured using a 10 cm visual analogue scale (VAS) at baseline and 30-minutes after treatment.
