For over 6 months I have been getting sharp pains in my ribs, sometimes my ribs feel really tight and I find it hard to breath and sometimes its sharp stabbing pains or they just ache, they have become more regular recently, lasting for days. Recently I've been getting regular really sharp headaches, a constant sharp pain in the right side of my head if I cough or move too quickly. I also feel dizzy and sick. What could this be?
