I have delivered 5 months back , from 3 months I have a pain in lower left region n back , pain goes off after resting and comes if I do more physical activity like climbing steps n all , I have done a USG everything is normal but it came I have swelling in intestines so I consulted gastrointestinal doctor he said pain is not related to this it's muscle spasm as pain goes of aster resting , he gave cyclopam and neorelax tab for 5 days for 5 days I was all fine and now after finishing a tab again I have mild pain if I do physical activities, I'm breastfeeding and so confused with the things , what could be the reason for a pain n what is the solution for it ?
