Hi, I'm a 24 year old female, I have had chronic lymphangitis for the past year and a half and my health has only been getting worse. The docs send me for blood tests every time I get sick but no indication as to what could cause chronic lymphangitis. I've just been for a scan and lymph node in my neck measures 13.5mmx5.6mm. I've also developed new allergies (jewelry, certain foods..) and the whole left side of my body swells up when I get sick now. My doctor has told me to do biopsy, but the docs at hospital have sent me for sonars and blood tests (they suspect a serious infection or lymphoma), any advice or suggestions would be appreciated.
