Really worried about 9 year old son. He is a known asthmatic, had various hospital admissions anyway to cut a long story short he had a chest xray which showed lymph nodes in his chest area after bloods and another xray (and being told it MIGHT be lymphoma) he was sent home and to come back month's later. This was January last year. He has antibiotic which made the swelling in in the chest go down, 3 weeks ago had another xray to show it had grown in size again. They don't know what it is and don't seem in any hurry to find out what it is!! Has anyone else had this and what can i do?!!
