If you have a large bony bump on the side of the joint below your big toe then you quite possibly do have a bunion. It is one of the most common foot disorders to occur. The bony lump may get larger over time and it may or may not be painful.
You are best to get advice from your Podiatrist sooner than later as the condition is progressive. At Mooroolbark Podiatry we can give advice in regards to causes, footwear, foot biomechanics, orthotics and pain management.
