Widsom teeth questions?

I'm 17 and i think my wisdom teeth are coming in. I already have my 12 yr old molars (ie. second molars) in. My lower left and right wisdom tooth area is alittle swollen and achy and this morning i looked at my upper left wisdom tooth area and it was more swollen than yesterday and it's beginning to ache too. They look to be getting alittle more swollen everyday. There is no pain, just ON and OFF aching. So does it sound like my wisdom teeth are coming in? Should i go to the dentist or just stop thinking about it? Also i have TMJ on my right side, Would it hurt real bad to have my wisdom teeth taken out with TMJ?
