Hi, An anesthetic/steroid mix used for vaginal trigger point injection may cause weight gain in some individuals, but this is not a common side effect. The steroid component of the mixture may increase appetite and fluid retention, which could potentially lead to weight gain in some people. However, the amount of steroid in the injection is generally very small and is unlikely to cause significant weight gain. It s important to note that weight gain can be caused by a variety of factors, including diet, physical activity level, hormonal changes, and other medications. If you are concerned about weight gain, you may want to discuss your concerns with your healthcare provider. They can help you evaluate your overall health and make recommendations for diet and exercise to maintain a healthy weight. In general, the use of an anesthetic/steroid mix for vaginal trigger point injection is considered safe and effective for the treatment of vaginal pain. Your healthcare provider can help you understand the benefits and risks of this treatment and answer any questions you may have. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
