humpy.....thank you very much for that interesting update.
Focal myositis.....I had never heard of this before and had to look it up.
Pseudo-tumour is a well recognized condition and I have had limited experience of it's treatment.
Neurology Hospital, Queens Square...on of the best Neurology Units in the world...you will get superb treatment. ( There is a very nice pub on the corner of Queens Square opposite the hospital that does great pub lunches)
This is a benign condition....nothing at all to do with malignancy.
The treatment will be surgical excision and the prognosis is good.
Thanks again for your feedback and please keep me informed as I am very interested.
