While there may be some slight discomfort, most patients tolerate the procedure very well and with minimal pain. The procedure is done in office and may use local anesthetic to minimize any discomfort. Post-injection soreness at the injection site is sometimes present because of an inflammatory response caused by the therapy. Most patients notice some level of improvement by 2-6 weeks following BMC. Increased stability and strength are typically reported along with the decrease in pain. A second level of benefits may be obtained between 6 weeks and 3months. Patients are encouraged to remain active with a functional rehabilitation program and strengthen surrounding muscles during this period.
