I'm 24, and have always considered myself quite healthy. However, some months ago my lower back began bothering me when sitting, standing or lying for a long time (though usually not when moving or stretching) A few days ago the right side of my lower back began to feel sensitive, and then I developed some patches of pimples (some bunched together, and also some apart), a sort of rash. Since then the back pain seems to be drowned by this other feeling of sensitivity of skin and some prickling of the lower right hand side back.
Do you think these two problems are connected? I spend a lot of time sitting now, so I suppose I ought to excercise lower back muscles, to strengthen them to hold up the rest of me.
