Acupuncture teaches us that everyone is unique and different. Therefore, the response to treatment can differ considerably from person to person, and it also depends how longstanding the condition is.  However, in most cases, you will experience significant relief after a few acupuncture treatments. Chinese Medicine aims to correct the root cause of the condition and not just the symptoms, so as a general guideline, I advise 4-6 sessions over a period of 4-6 weeks.
