Multiple sclerosis (MS) is a chronic disease that affects the central nervous system, particularly the brain and spinal cord. Symptoms vary widely from person to person and can come and go or gradually worsen over time. Here are some common signs and symptoms: Fatigue: One of the most common symptoms, often severe enough to affect daily activities. Numbness or Tingling: Typically occurs in the face, arms, legs, or fingers. Weakness: May be felt in one or more limbs, often accompanied by difficulty with coordination and balance. Visual Disturbances: Blurred or double vision, optic neuritis (pain and temporary vision loss), and involuntary eye movements. Muscle Spasms and Spasticity: Muscle stiffness and spasms, often in the legs, can be painful. Mobility Problems: Difficulty walking, balance issues, and in some cases, partial or complete paralysis. Pain: Chronic pain, such as neuropathic pain (burning, stabbing sensations), is common. Cognitive Changes: Memory issues, difficulty concentrating, and slower processing speed. Bladder and Bowel Issues: Frequent urination, incontinence, constipation, or bowel incontinence. Speech and Swallowing Problems: Slurred speech, difficulty swallowing, and changes in voice tone. Depression and Mood Swings: Anxiety, depression, and mood changes are common due to the neurological impact of MS. Heat Sensitivity: Many people with MS find that their symptoms worsen with exposure to heat.
