G'day I Am A Pest Controller And Every Time I

G'day I am a pest controller and every time I carry out a termite treatment which means coming in contact with soil in some way or another I feel if so something is crawling on me. It happens when my feet (which I always have shoes on) come in contact with soil I feel like something is entering through my skin. I get swelling around my eyes the right knee swell up and becomes very painful I get headaches and break out in little blisters blind pips over all parts of my body. Sometimes I scabies cream on them and they disappear not always my throat is grow key. I take drugs and when I don't take them it goes away but then I become very tired again no energy. Can you help me?
