I almost assuredly have tarsal tunnel syndrome that has escavated to be pain up to my right knee. My concern is what is apt to be the hard lump under the palm of my foot? I had a morton neuroma surgery about 2 yeears ago. I had gone in for this other problem that has gotten worse. About 30 years ago I had cortisone shots periodically for a possible cyst in the right foot. It feels like a hard area larger than a quarter. I am 5 5 and 140. Thank-you. I have been through all the conservative measures such as boot for 3 months, etc. and find the prognosis of successful surgery fo r a TTS only at about 50% successful???
Hello, The symptoms seem to be related to tarsal tunnel syn Chat Doctor.  I suggest using conservative treatment such as Ibuprofen to relieve the pain. Resting, icing, compression, and elevation, known as the RICE treatment, may also help reduce swelling and inflammation. If the symptoms continue, I suggest consulting an orthopedist for further evaluation. Hope I have answered your question. Let me know if I can assist you further.
