Lump in arch of foot
by Deirdre
(Italy)
I have a lump in the arch of my foot which I first noticed after experiencing some arch pain (following the start-up of a running and swimming routine). The lump got bigger, and I eventually had an ultrasound performed. I was told there was no nodule (fibroma or such), but rather inflammation of the tendon which had caused it to thicken. I have a bit of the same pain in my other foot, in the arch, but mostly the classic heel pain. There is no thickening of the arch in that foot.
I am perplexed because I keep seeing plantar fasciitis as being connected only to heel pain and never with the mention of a thickening of the tendon in the arch that is palpable. What can I do to treat this? The doc who performed the ultrasound told me I would most likely have to have physical therapy. What do you think I have, and what can I do at home to remedy it?
Thank you!

RESPONSEHi Deirdre,
Most people associate plantarfasciitis with inflammation of the plantar fascial ligament that attaches into the heel causing heel pain. However, the plantarfascial ligament extends all the way to the ball of the foot and attaches just behind the metatarsal heads.
So you can have plantarfasciitis any where from the heel to almost the ball of the foot. Apparently you have it at mid arch.
This would be a result of you over stretching the ligament as a result of your athletic activity. The problem is, that walking and of course exercise both keep aggravating the ligament so it never has the chance to get better.
Yes, physical therapy could be helpful. In addition you should consider taking anti-inflammatory medication (if you can tolerate such medication) in an effort to reduce the inflammation of the ligament.
Lastly you should also consider wearing an orthotic device whose purpose is to prevent the ligament from over stretching when exerising (and walking).
You can have all the physical therapy in the world along with medication, but unless you control the over stretching of the ligament through the use of an orthotic, you will have difficulty eliminating the problem.
