i have had severe itching all over my body now for almost 2 months. have to take benadryl 100mg every day to ease the itching. this past week i had on a tee shirt and was playing wii bowling with my dad. played for 7 hours straight. the first hour, i am right handed, my upper arm naturally would rub against my right side as i made the "bowling throw". after the first hour, i noticed some redness, almost raised, like a hive, half dollar size. at the end of 7 hours, it had turned into dark blue/purple bruising covering my entire bicep, bigger than the size of an apple. now, a couple days later i have noticed a hard lump inside of the bruise. it is also painful. continue to itch all over my body. havent changed soaps, lotions, detergents, meds. also very fatigued, depressed more, and bleeding gums. i am worried i may have some type of leukemia.
