Evening,

Roughly six weeks ago I had a rash they said was chicken pox however the itching is extremely bad all over with no rash. I am also covered in bruises large all over my body , had everything done full blood count fine waiting for kidney results , I have had a raised crp marker and a chest X-ray that was clear. I am concerned about multiple melanoma or blood cancer, can your bloods show normal with these? I am a 27 year old women. 
 

Thanks
