I'm a 36 year old male with Type 1 diabetes and end stage renal disease (on dialysis). Like any guy, I masturbate. Over the last few months, I have started experiencing pain after orgasm. It started as a throbbing chest pain. Then the throbbing expanded to my chest and upper back. Now it is in my chest, upper back, and the right side of my neck. The throbbing is happening with my heartbeat, but my pulse isn't racing. It just feels like my heart is trying to pound its way out of me. The pain lasts for about one to two minutes, then goes away. Should I be worried? Any advice would be great. Thanks
