A few weeks ago I noticed knots near each shoulder in my back. They are very painful and will not go away. A week and a half ago or so I started feeling like my shoulders were sunburnt, but as far as I can tell there is no rash or anything present. Sometimes it even feels like those two spots are tingling. I noticed last night that at those spots I have odly shaped moles. I think they are moles...but they are flat. One is shaped like an upside down heart and the other is like a long skinny oval. Neither one is very big.
Does this sound like something I should have checked out? I should also mention that I am very fair skinned and have gotten very sunburnt many times in the past.
Thanks!

Yes you really should have them checked out for sure.
