Hi, you should look at the nodes as a clue as to what is causing your main condition - so that tends toward autoimmune or inflammatory, and not lymphoma. The nodes are just a side issue for you.
they have not really explained anything as they said they do not know what is the cause for the spasms which are so bad that at times it causes my legs to collapse from under me. As well as I have had times when one leg or arm would just go numb and would be of no use and then would slowly go bakc to almost normal. When I presented with the spasms what the doctors were looking for was MS the MRI ruled that out for them so they are currently investigating for a neurological problem or auto immune but so far no proper explanation has been given as the findings of the MRI do not account for the magnitude of the pain nor the temporary parylsis in my limbs.
In general, it sounds like you have a bulging disc (which is probably what is causing your symptoms). You've probably already figured that part out and are mostly inquiring about the last line of the report? I think superficial lymph nodes just means they were apparent in the scan. I don't think they were necessarily enlarged or a cause for concern. What was your doctors explanation?
