[|Human|] I have had two surgeries on my left foot, the first was to put 4 screws and a plate due to foot pain and he also cleaned out my joints. the second surgery was to add some balls in my foot due to the joint being worn out, he took the 4 screws and plate out due to the screws being broke. I have two knots in the bottom of my foot and my foot is hurting constantly. I am waiting for a MRI that should have been weeks ago but the doctor wanted to wait. what could this be
[|AI|]  There is a muscle on the inside arch of your foot that runs from the inside of the heel bone to the inside of your big toe. This muscle pulls your big toe in--toward the midline of your body. If you are sure that the bump is in a muscle, the abductor halls muscle is the most likely candidate. It could have been injured and now wants to cramp. If the bump you see is bluish it could be a collection of blood from the injury--a hematoma. Massage will help the body reduce this. Another possibility is an injury to the particular bone in the same general area. This would feel harder than the muscle and will not go away with time or massage. Finally, and least likely if the bump is truly on the inside of the arch and not on the bottom of the arch, is a condition called plantar fibromatosis. This would nothing to do with a muscle or bone but rather a growth in the plantar fascia. This will also not respond to massage and time.
