Sildigra 100 mg is a generic form of sildenafil, commonly used to treat erectile dysfunction (ED). One of the potential side effects of sildenafil, including Sildigra 100 mg, is back pain. This side effect is relatively rare but can occur due to the way the drug works in the body.

Sildenafil works by increasing blood flow to specific areas, including the genitals, by relaxing blood vessels. However, it also causes relaxation in other smooth muscle tissues, such as those in the blood vessels of the back. In some people, this may lead to an imbalance in blood flow or muscular tension, resulting in discomfort or pain in the back.

Additionally, sildenafil can affect the nitric oxide pathways, which are involved in muscle relaxation and pain perception. As a result, some individuals might experience pain or discomfort in the lower back as a side effect.
