... weeks ago. He says his fingers are tingling and/or slightly hurting and his left shoulder is acachie. He has neuropathy and his diebtis has been moderately controlled. I had him take a medical leave from work after his last 2 stents to get his diebtis under control and his overall health. Should I be concerned about his heart? Is tingling fingers a sign of heart problems? Im keeping a close eye on the achie shoulder because I understand that could be a sign.
