Main Symptoms of Kidney Cyst

A kidney cyst is a fluid-filled bubble on or in the kidney. Most stay small and silent, but when they grow or bleed they start whispering warnings. Flank ache is the usual first talker. It feels like a dull bruise just below the ribs or a sudden cramp if the cyst stretches fast. Urinary changes can tag along. You may notice more trips, a weaker stream, or the sense the bladder never fully empties. Blood in the urine sometimes shows. The color may be light pink or tea-brown, often painless and spotted only in the first morning pee. A swollen... Learn more

Main Symptoms of Cystitis

Cystitis is an infection or irritation of the bladder lining. It comes on fast and makes the simple act of peeing feel like a fire drill. Burning is the headline. The moment urine touches the opening it stings, and the sting lingers for a few seconds after the stream stops. Urgency doubles. You sprint to the bathroom every twenty minutes, but only a few spoonfuls come out, leaving you feeling cheated. Cramping sits low. A dull ache hangs just above the pubic bone and eases right after you empty, then creeps back as the bladder fills again. Cloud or color... Learn more

Main Symptoms of Urinary Tract Infection

A urinary tract infection (UTI) means germs have set up camp somewhere along the pee system—bladder, urethra, or kidneys. The signs are hard to miss and usually hit fast. Burning is the first clue. It feels like hot sauce on the pee hole and is worst at the start of the stream. Urge doubles. You dash to the bathroom every twenty minutes, but only a spoonful comes out. Pain moves low. There’s a heavy, crampy ache above the pubic bone that eases right after you go. Cloud or smell shows up. The urine looks milky, smells foul, or turns light... Learn more

Main Symptoms of Hydronephrosis

Hydronephrosis is a build-up of urine inside the kidney, usually because the drainage pipe is blocked or too narrow. Pressure stretches the kidney like a water balloon and sends quiet but clear warnings. Flank pain is the headline. It feels like a deep ache just below the ribs or a sudden cramp that can shoot into the groin when the blockage shifts. Urinary changes follow. You may notice less urine, a weak stream, or the need to go more often with only small amounts coming out. Blood in the urine can appear. The color may be light pink or cola-brown,... Learn more

Main Symptoms of Tremor

Tremor is a rhythmic shake you can’t ignore. It shows up when muscles work or rest, and it usually starts small—then steals the spotlight. The first tell is a fine bob in the fingers. You notice your hand wiggles while pouring coffee, and the stream turns into tiny splashes. Writing changes next. Letters become shaky and larger, and the pen digs harder into the page. Rest tremor appears when the hand is still. You sit watching TV and see your thumb and forefinger rolling a pill that isn’t there. Action tremor jumps out on purpose. Lifting a spoon, threading a...
