You may feel improvement in your condition (usually pain reduction) between the first and third treatments. For some more chronic conditions it may take up to 6 visits to feel the benefits of laser therapy. Not everyone responds to laser therapy and results cannot be guaranteed. 
MLS laser therapy can penetrate 3-4 cm to heal tissue. Other lasers may only penetrate 1-2 mm, and may not reach your pain.
Are the results long lasting?
MLS laser therapy is about healing. It’s not about masking or covering up a condition. When you feel better from this therapy, it’s because you are better. Therefore results have been found to be quite long-lasting.
Can it be used in conjunction with other forms of treatment?
Yes, MLS laser therapy is sometimes more effective when combined with other forms of therapy, including physical therapy, chiropractic, massage, soft tissue mobilization, electrotherapy and following surgery.
