i ve had an ongoing series of problems of late and was wondering if they could all be related. it started with shortness of breath followed by some dizziness. i have a heart murmur so my doctors checked that first. echo, esopphageal echo, stress test(both nuclear and not). there is nothing definitive there. the dizziness eventually went away. the shortness of breath returns with strenuous physical activity. it is accompanied by pain in my upper right chest and back, leading to a great deal of pain in my right shoulder, which gradually fades if i stop all physical activity. next symptom, related or not, i got some swelling in my left leg. it looks like the fist toe got injured(redness, swelling). i don t remember injuring it and it does not hurt. that led to swelling in the foot, then ankle, then calf. it was diagnosed as an infection, but antibiotics have not helped. now my right leg is swelling also. blood work shows no sign of diabetes. also now i am experiencing excessive need to urinate(very new-have not yet talked to doctor yet). excessive need in frequency- volume is always very small. can there be something wrong with my kidneys? I will discuss this with my doctor when i next see him, but the need to urinate has kept me up tonight so i figured i d try this. my e-mail is YYYY@YYYY .
