I m a 17 year old teenage girl from Australia and more often than not I find myself outside without protection in the sun for a while without even realizing it. I will walk outside only anticipating to spend a few minutes and find myself outside for hours in the hot sun. I have multiple moles on my back and a few seem to be darker and have a lighter circle around them. I often use tanning oil which has SPF 30+ in it and I ve only ever been burnt once, I have a rather light olive skin tone. Lately I ve had a lot of back pain particularly around the area s of my moles and these last 2 days its started to become unbearable to the point where I can t lift things that I used to be able to lift cause its causing pain down the center of my back. Should I see a specialist about my moles? I ve had them for as long as I can remember and just never bothered to get them checked out and being young I figure that there would be nothing wrong with me as I m quite fit and healthy for my age. Do you think this could be a serious problem?
