Hard nodules in neck and groin

So I was wondering if anyone could help me out here. About a year ago I noticed a hard, painless, non-movable lump on the right side about midway up my neck so I thought it was an infection and thought nothing of it Now a year later I still have that lump on my neck but now I discovered another lump in my left groin area. Same thing; hard, painless and doesn't move. Both of this lumps are probably about 1-1.5 cm in size.Also about a month ago I got this red rash on my face that covered half my nose and over under my right eye and down towards my mouth somewhat. I have also been very fatigued but that could just be the college life taking its toll on me. I also sweat at night but I'm not sure if that is because the dorms are warm. Is there any cause for concern?
