Hi I was in the gym earlier training my back muscles and legs, I took a shower afterwards and noticed a bruise the size of a penny on my left forearm near my inner elbow I touched it and over 15seconds it spread into the shape of a pear, it s following my artery towards my hand, it doesn t hurt but it tingles and I feel dizzy, in the past I had a blood infection which shown on my finger, but I don t know what this. Thought I d ask on here before going hospital, thanks.
