I have been experiencing itching on and off every month for at least a year, this has developed into a rash on elbows, legs, covering my back and scalp. I am constantly scratching and have now developed an extremely large and painful swelling in a lymph node at the top of my jaw. This node is solid and larger than 2cm. The nodes in front of both ears are swollen and marble like to touch also. 
 

I am constantly tired and have seen my GP numerous times with the same issue. They performed full blood tests and all came back within normal range apart from immunoglobulin e which was just above normal range. I have another appointment booked for Thursday. 
 

I am genuinely concerned that I have some form of cancer and want to know if anyone else has experienced the same or similar symptoms. 
 

well wishes to all.
