What Causes Chronic Cough Along With Wheezing?

I have been sick for a couple months with a cough, wet for a long time, the bark is gone but I m still clearing out really dark grey mucus and I also wheezed for a solid month but juet assumed it was apart of a cold.nI woke up with night sweats and a chill today that would not go away. I smoke pot so maintain somewhat of an appetite but it s really not but I am eating. I m more concerned about the pain that started s few days ago in my right lower back. I started my period 3 days ago so I thought the pain was related but today it s radiated toward my middle back around my hip and comes unbearable then goes awa. I have not done anything to pull a muscle. I keep stretching in attempts to make it better but it s not helping. It s a lot like a kidney infection pain I had and I m worried I may have another.
