Early symptoms of cystitis: 1. Irritability: Crying over the slightest trifle may not match your personality. This requires checking the thyroid gland, the central nervous system is most sensitive to thyroid hormone imbalance. 2, the initial symptoms of cystitis: easily agitated, irritable, crying, insomnia, and a good appetite but increasingly thin, menstrual disorders. 3, back pain: this may be cystitis or adnexitis. You should go to the hospital for blood and urine tests, and if needed, a cystoscopy or gynecological examination. This is the time to drink more water and avoid spicy, spice-containing foods for cystitis patients. Anti-inflammatory treatment and physical therapy are available. 4. Excessive sweating: more sweating than usual may be a plant nervous disorder. If ordinary sedatives do not work, it is time to see a doctor. Acute cystitis: burning pain in the urethra during urination, frequent urination, often accompanied by urinary urgency, in severe cases similar to urinary incontinence, urinary frequency and urgency are often particularly pronounced, and there can be pain in the lower abdomen at the end of urination. The urine is cloudy, with a rotten odor, pus cells, and sometimes hematuria, which is often obvious at the end of urination. Pain in the suprapubic region is obvious when the bladder is full, and sometimes pain in the urethra and perineum is also present, which is relieved after urination, and hematuria may occasionally appear. Mild back pain is seen in some patients. When the inflammatory lesion is limited to the bladder mucosa, there is often no fever and leukocytosis in the blood, and systemic symptoms are mild or absent, with some patients experiencing fatigue. Acute cystitis has a short course, and if treated promptly with diuretic and anti-inflammatory pills, the symptoms disappear in about 1 week.
