My husband is 62 has been sick for about 10 days with cough and congestion but that seems to finally be getting better. 4 days ago though his stomach started hurting on the right side like right at the top of it then, this afternoon his back started hurting a sharp pain in the left lower side the most, but also a bit all the way across the bottom. He has had 2 stints put in about 7 yrs. ago and he had back surgery about 12 yrs. ago. His blood pressure is 171/86 and his pulse is 115 sitting. Any ideas?
