Hi!! I am 48 and am having trouble with my right knee. I clean our church and so am on my knees a lot, i have a bump below my knee cap on right side of my leg, the more i walk or do the worse it feels, throbbing pain, almost like a shin splint, my leg swells and i have to rest it, what is going on? thank you, i have no health insurance, and very active and busy, can not pay, but thank you! have a great day!
