What you will notice

Weeks 1 to 2: little to feel at first; some notice the burning eases at night. Weeks 2 to 4: pain lower, sleep easier, and automatic signals such as bowel warning may start to return. Weeks 4 to 8, after the course: nerves keep regrowing, so feeling and function often keep improving. Longer: a second 28-day round can build further on the first.
