Hi. I Have Been Experiencing Pain In My Right Side

Hi. I have been experiencing pain in my right side . I have had a hernia in the past so I think I may be experiencing that again. I have pain, bloating, sometime I have a hard lump that protrudes in the area of discomfort. I talked with my doc at my last physical which was in September of 15, she said she thought it was sludge in my gall bladder. It felt better for a while after that, but since January it is acting up again.
