Hand shivering and feelings of weakness are usually not caused directly by reducing masturbation. These symptoms more commonly happen due to stress, anxiety, poor sleep, overthinking, weakness from a poor diet, vitamin deficiencies, excess caffeine, thyroid imbalance, low blood sugar, or nerve-related conditions. Many people become very focused on body sensations after changing habits, which can make normal shaking feel stronger and more worrying. If the trembling happens during stress, nervousness, fatigue, or while holding objects, it may be related to anxiety or muscle fatigue rather than damage to the nerves. Lack of proper sleep, dehydration, and irregular eating can also increase shakiness and weakness. Improvement may come from regular sleep, balanced meals, exercise, hydration, reducing caffeine, and stress control. Doctors may sometimes suggest tests such as vitamin B12, vitamin D, thyroid profile, blood sugar, or haemoglobin if symptoms continue. Medicines depend on the actual cause and are not always needed. Sudden severe weakness, difficulty walking, speech problems, or tremors spreading to the whole body should be checked properly.

Most men who worry about their size actually fall within the normal average range (3 to 5 inches flaccid, 5 to 6 inches erect). Currently, no scientifically proven pills, creams, or exercises safely or permanently increase penis size; over-the-counter products are often unproven and risky. Surgical options, like phalloplasty, carry severe risks such as scarring, loss of sensation, and erectile dysfunction, and are typically reserved only for a medical condition called micropenis. I highly recommend consulting a urologist for an objective evaluation or a counselor to help address any anxiety regarding your body image.
