If the area described doesn't match an energy point on the bladder meridian (check it out with a diagram) it is usually related to a pocket of congestion in the colon (ascending) where a similar lump is formed. To be sure, do 1-2 colonics and see if it goes down. Please don't touch or squeeze it, it will only go harder this way as you damage cells and cause scar tissue and lymph edema. It is better to place urinary poultices (from morning urine) there during nightime, until swelling is gone.
