Over the past 6 months, I have had lumps (of varying sizes) along my shin bone and even down to my ankle and into my kneecap. They move around, and vanish and then reappear. Currently there are only a few small ones, hardly as noticeable as they were before, but they are indeed there. I just recently got bloodwork and xrays done, and they say all is normal and to visit a specialist. Any ideas before I spend a fortune?
