Okay - here I am.
You must have had a neuroma in your foot at one time - your doctor wrote that you have a history of a neuroma. A Morton's neuroma is not actually a tumor, but a thickening of the tissue that surrounds the digital nerve leading to the toes. I don't see this on the MRI, so you must have had that removed. You have reactive marrow edema because of the trauma that was caused when you ripped the medial cord from the plantar fascia.
If you look at the picture below, you can see how the tendon are connected to the calcaneous (heel bone) - this is called the plantar fascia tendon - you have a high grade partial thickness tear in the medial one - the one closest to the instep.
You also have a tiny accessory navicular bone. This is also located up further, by the side and before the beginning of the big toe. Having an extra bone here is not unusual (about 50% of all people have this). This may or may not be giving you a problem too, but it was picked up on the MRI. It doesn't show any "signals" which would mean there is swelling or edema. Look at the picture below:
Other than the tear in your heel area, which is quite significant because there is marrow edema (indicating the trauma of the tendon pulling from the bone), you have no arthritic degenerative findings, which is a very good sign.
You didn't say what the doctor suggests in fixing this problem. Usually they like to fix the tear so that you can have mobility again. I hope you are elevating your foot above your heart up on pillows as much as possible, including when you are sleeping, so that you bring down as much swelling as possible. Actually, I don't see any evidence of soft tissue swelling in the MRI, but the MRI is most appropriate in picking up fractures, spaces between the bones, cartilage, ligaments and tendons.
If you have any questions, please let me know.
