I am 34 weeks pregnant with my second baby, 4yrs after first one. I am having immense back pain. So much that i am continually limping. Pain originates from central-right side of buttocks, moves down to the 4th toe of the right leg through side of the right leg. Feels like the pain is from the leg joint, but I am not very sure. Constant pain and quite immense. Right leg is little swollen. So much that turning sides, even while standing is a task. Cannot walk for long without holding something. Getting up from bed is another task - takes around 5-7 minutes literally. Hot water bag doesn't help. Volini helps momentary. Please suggest what to do..
