How quickly does physiotherapy work? In general, you should attend physical therapy until you reach your PT goals or until your therapist—and you—decide that your condition is severe enough that your goals need to be re-evaluated. Typically, it takes about 6 to 8 weeks for soft tissue to heal, so your course of PT may last about that long. Generally, Deep Tissue Laser Therapy and Tecar Therapy heals from inside out. and in almost 25-35 sittings, pain due to spine problems i.e. spinal canal stenosis, sciatica, slip disc, disc bulge, disc herniation , disc rupture, nerve injury, nerve impingement, taut bands, arthritis, osteoarthritis, rheumatoid arthritis, sero-negative arthritis, joint pains, plantarfascitis, frozen shoulder, neck pain, back pain, radiculopathy etc heals completely.
