I Dipped My Penis Tip In Dettol. The Dettol Went

I dipped my penis tip in dettol. The dettol went into my urine opening. Extremely terrible burning and hardening of my penis tip flesh occurred. I immediately with my trembling hands washed with water and drant more than a litre water so that I urinate. After that I consulted general physician who prescribed Nerosine cream tube to be applied inside opening. I feel hardening and burning still and the tip flesh has loosened its softness. Please help and prescribe treatment.
