5. Breathlessness
A little amount of breathlessness after an intense workout, a run or other such similar activities is normal. However, if you feel short of breath without exerting yourself, your kidneys might be in trouble (5). Why this happens is dependent on two reasons. One is when fluid builds up in your lungs and the other is due to the subsequent anemia, which causes a deficiency of oxygen in your body. Both of these are caused by improperly functioning kidneys.
6. Backache
Kidneys that are on the verge of failing can also give rise to back pain. This kind of backache is deep and is caused in the lower sides of the back, below the ribcage (6). Due to its close proximity to the following areas, you may feel it in your hips or groin. Such aches are generally as a result of cysts in your kidneys and can be accompanied by fever, vomiting, and frequent urination.
