Background: Breast feeding problems are encountered in up to 80% of mother and infant. Objective: To assess the effectiveness of olive oil massage in reducing breast engorgement and pain among postnatal mothers with LSCS admitted in selected hospital at Meerut”. Materials and Methods: A quantitative approach with Quasi experimental, Non randomized control group design was selected as a research design. A total no of 60 postnatal mothers with LSCS who are suffering from breast engorgement and pain were purposively selected. 30 for experimental group and 30 for control group. Breast engorgement intensity was assessed by using six-point engorgement scale and breast pain intensity by a numerical pain rating scale. Olive oil massage was applied on an engorged and painful breast area for twice a day ,for duration of 10-15 min in experimental group. For control group no intervention was given. Posttest was assessed after 30 min of second intervention from both the group. Result: The mean post-test score of experimental and control group for both right and left breast shows 79% reduction in engorgement score, this is statistically significant as evident from p 0.05. Conclusion: Based on the findings the following conclusion can be drawn that application of olive oil massage is found effective in reducing breast engorgement and breast pain among postnatal mothers with LSCS.
