Hello, I have been experiencing very tender and sore ribs, shoulder blades, back, and hips. Particularly at night. I also get some pain in my knee joints. My hips and butt get very sorry from sitting on ground even for short periods of time, and I am having neck pain. I sometimes am getting little tingles. I have cold symptoms, very sore throat, runny nose, balls of mucus coming out of my mouth, etc. I am also having bad headaches/migraines. Could this new found muscle pain etc be caused my my period? If not, do I have an underlying condition?
