I am very sorry, but this is a board of nurses, most of whom have not the authority to diagnose or recommend treatment for any condition.
Please re-read the Terms of Service if you are unclear about the rule about the giving/receiving of medical advice.
There are a lot things that could be related to this pain. You won't know for sure until you visit a qualified health care provider and investigate it. There is no shortcut we can offer here. Please, make an appt with your doctor/nurse practicioner at your earliest opportunity.
I wish you luck and I hope all turns out to be ok. Take care.
