I am a 53 year old man. I have constant night sweats along with sporadic muscle cramps in the feet ,calves, thighs ribs and biceps, and back. My medical history is left and right shoulder rotator cuff surgeries. Stenosis of the c5,7,spine. Carpel tunnel both wrists., trigger thumb both hands, Had several silent heart attacks this last December . Had stents . Now taking blood thinners, blood pressure meds , b-12 , fish oil. 24hr nitro plus nitro as needed. Let me clarify that the night sweats/ cramps were happening before the heart attack and taking all the meds. Lately I ve also been loosing my balance and especially when driving on curvy roads feel off balance. Had intense tingling / shooting pain in my feet after walking or standing for like 15/20 minutes. I am a retired US Marine (21years) and recently retired from law enforcement. Any ideals?
