First problem:
just last night, I suddenly had a cold feeling. My body started shivering uncontrollably. Along with these shivers, my body started aching. These pains were present in my neck, back, legs, and head. My eyes became a little sensitive to light. I don't have a thermometer, so I can't accurately know what my temperature is. I did feel my neck and forehead, and I was relatively warm. But that might be resulted from my attempts to stay warm and to stop the shivering. I woke up this morning thinking all would be well, but my body kept aching. I had difficulty getting outta bad, and I can't walk in a straight light. I always need support from a wall, table, or anything I can get my hands on.

Second problem:
for the past few months, or even the past year, i've noticed that I have been urinating quite frequently. Everytime I see a toilet, I get the urge to urinate. When i'm done, it feels as if I didn't "finish." with that, I end up visiting the restroom again within the next half hour or less. I saw commercials of frequent urinating can be caused by prostate cancer. But i'm only an 18 year old male. Having thoughts about me having prostate cancer scares me.

I need help or advice with my two problems.
