Hi, I have pain in right shoulder and side of shoulder .i had small lumps in under arm when I pressed that and put some hot pad and did some shoulder rotation next day I got this shoulder pain .i thought due to calcium deficiency and taking calcium tabs from 3 days. It's been 5 days still I have the pain some times like doing heavy work or when putting pressure on hand. I got my periods 4 days early. Is this all because of my periods or I did shoulder rotation because of that? And also I have pain in my upper back when waking up in the morning daily. Thank you.
