swollen groin lymph nodes

I have swollen lymph glands on both sides of my hips and have developed a rash on my back that my doctor believes to be Shingles, I am very concerned and awaiting blood work on Monday.  Do you have any thoughts on how serious this could be, I am a nervous wreck and can't shake bad feelings.  I am 33 years old and physically fit.  I have searched and can't find any bite marks or obvious reasons for the swelling.  Thanks for any advice.

Lymph nodes in that area are usually due to infection along the legs, STD, or malignancy. Think of your past history if you have any reason to believe they are related to the first two. If malignancy is deemed possible – your doctor would recommend a biopsy, that is the only way to know for sure. In the meantime, take heart – if you are physically fit, you need to remain so as this would help your chances of recovery whatever the diagnosis is.
