What could it be? Please note that I am currently grieving, someone in my life has committed suicide, so maybe it's anxiety?

It is important to note that if you are experiencing physical pain, it is necessary to undergo a medical investigation before attributing it to anxiety. Whether or not it is related to a loss by suicide, it is important to seek help for grief if you are experiencing physical, psychological, or emotional symptoms. It is important to address any issues with a healthcare professional to properly address and manage your symptoms.
