question: Hi my boyfriend has had a tiny bruise on his lower back for about 3-5 months now and it doesnt hurt but its a tad itchy. He doesnt bruise easily at all either so its kinda odd for him and an odd place. He has also always kinda had night sweats but lately they happen more frequintly and quite alot of sweat. Im just wondering if this is a cause for concern because Ive been researching that these can be stages of different blood cancers or clotting. Thank you so much
