For the past 3 weeks I've had the symptoms: Started; With a red spotty rash and a few small yellow/brown bruises... The rash went away within 30 mins and the bruises went away within 3 days. I got a rash again a few days later, on my neck, arms and legs. This time the rash was lumpy. Sore muscles for a few days. Flashing joint pain now and then. Bladder pain. Tender areas on my body. Achy legs especially at night. Muscle twitching. Fast heart beat at night for a few minutes. Eye twitching. Weeing more. Diarrhea. Achy legs, especially at night. Headaches. Sore cheek bones. Neck pain. Shoulder pain. Back pain. Hip pain. Burning sensation. Lights when blink. Is it possible leukemia could cause all these symptoms? At the time these start happening I had a sore throat. I went to the walk in centre and she said I have a viral infection. Also over the Christmas I had a throat infect and left it to go away on it's own. Could that be the cause? Because the lymph nodes in my neck are still there from it, but much smaller. And I haven't got them anywhere else. These pains aren't constant, they come and go. When I'm moving around doing things I don't seem to get pain. But when I'm just sitting my legs ache. And when I do get pain they are flashing pains. Also when i sit a certain way I'll go stiff for a minute until I move. I'm 19. Could it be linked to my diet? Because I hardly eat healthy. I always eat chocolate stuff. And not much of my 5 a day. I suffer anxiety and I'm constantly worried I have cancer. When I get the bruises it's only one at a time. I don't get loads of them all over. They fade quite quickly 2. And they just appear on my lower legs. I haven't or got a fever also.
