Hi, Thanks for query to My HCM virtual Clinic And welcome to HCM services.
I studied all details of your query.
I understood your health concerns about causes of knots in the back-
Based on facts of your query,it seems that-you have multiple FB granulomas with fibromas.
Moslty they have occured after the foreign bodies fixed underneath to your back skin./or they could be Sebaceous
cyst accompanied with such fibromas.
And these FB fibromas seem to move against the spine.
Hope this reply would help you in resolving this complex query and
anxiety with it.
Will appreciate your hitting thanks and writing excellent review comments to help needy visiting patients at HCM like you.
Welcome for any further query in this regards.
Good Day!!
