Male Baldness Info

I have been experiencing back pain and chest pain (the chest pain feels like someone is poking me in the middle and sometimes in the right side of the my chest). I went to the ER three days ago and they gave me a blood test (for my blood counts, cholesterol, and kidney), EKG, and a chest x ray.. everything came out normal.. my dad died two years ago and i have been in a lot of stress lately and most of the time i am having trouble falling asleep at night. Therefore, my doctor told me that it’s the stress and not being able to sleep at night that are causing all the back pains and chest pain. Also, I have been taking rogaine for my male pattern baldness. So i’m not sure if that’s another cause of my chest pain. I am a 20-year old man.. about to turn 21 this month.. can someone tell me why am i still getting chest pains and sometimes back pains?
thank u for your time.

I’m an 18 yar old male and for the last couple months have been experiencing something weird. I’m not sure if this is natural hair loss or not.
I will have a painful irrititation in random spots on my scalp and when I have that pain if I run my hand through that location or pull the hair around that location a few strands of hair usually easily come out.
I’m not noticing large bald spots or anything, and baldness runs on my father’s side, but is it supposed to happen like this and come out after scalp pain? I also have a small bump that popped on up on the back of my head and I’m not sure if it’s related. Also some very sensitive scalp on the back of my head. I can’t even really lay down on the back of my head to sleep.
