I Am A 34 Year Old Female And Have Experienced

I am a 34 year old female and have experienced large lumps in my armpits since high school, usually resulting in a trip to the doctor to have the lump lanced. About 4 yrs ago I began developing these lumps in my groin area again resulting in a trip to the doctor. I have recently noticed that my joints ache, especially my knees and wrists and i often experience pain in the bottom portion of my neck and upper leg pain. I have also suffered from cold sores since high school and in the past few years will have horrible outbreaks of canker sores, 4-5 at a time and also in the vaginal area. Does this sound like some type of autoimmune disease?
