My original post was with with regards to swollen lymph nodes giving 'cause for concern' after scan.  Yesterday, I had a blood test and a short time ago this evening the GP has phoned to say that my white blood cells are very low and I will be unable to fight off any infection at the moment.  I was trying to think positive since I was told about the 'cause for concern' and this site has been so good in helping me do that.  However, after the GPs call - I am sitting here in tears - especially when he said, again, the scan was 'cause for concern'.  I have an ENT appt first thing Monday morning with the hope they will do a biopsy.  The GP was hoping they would but could not say.  I cannot help but think the worst.  Thank you for listening - writing this is helping me to calm a little.
