Well, if 3lac is not working for you, you might want to consider LB12?? From your constipation, it seems that your colon and bowel is unhealthy and could the reason causing the pains?? I am not what 3lac contains but LB12 has 12 strains of LIVE bacteria with 5 colonizing strains. There are 3 strains of Bifidum bacteria and 2 are colonzing. They are very effective in clearing the colon n bowel of old debris, toxins and harmful bacteria.
Combined with flax hulls, they are very effective to help overcome constipation. Flax hulls containe both soluble and insoluble fibre. It is also a great immune system booster and very useful for your health.
