Thought I'd update here about my doctor's appointment. After exam the ortho foot doc says I have Morton's Neuroma - both feet - left far worse than right.
Nice little frosting on top of PN. I received injections of cortisone in both feet Monday. Today they are feeling better, but very sore. He explained I could have injections in 6 weeks again if needed. If it continued after that, surgery to remove the neuroma (the nerve). But was encouraging that shots usually worked.
It is comforting to have a diagnosis. I'd like to hear from anyone else who has had this problem on top of PN.
And, for those lumps on my feet - he explained we have muscle on top of our feet there and I have swollen muscle with maybe a small ganglion cyst. hmm? Whatever. Mystery solved I guess, except, of course, why I have PN.

warm wishes to all,
ML
