Whether or not acute trauma progresses to long-term effects probably depends on multiple factors that include the shock wave dose (i.e., the number of shock waves delivered, rate of delivery, power setting, acoustic characteristics of the particular lithotriptor, and frequency of retreatment), as well as certain intrinsic predisposing pathophysiologic risk factors.To address these concerns, the American Urological Association established the Shock Wave Lithotripsy Task Force to provide an expert opinion on the safety and risk-benefit ratio of ESWL. The task force published a white paper outlining their conclusions in 2009. They concluded the risk-benefit ratio remains favorable for many people. The advantages of ESWL include its noninvasive nature, the fact that it is technically easy to treat most upper urinary tract calculi, and that, at least acutely, it is a well-tolerated, low-morbidity treatment for the vast majority of people. However, they recommended slowing the shock wave firing rate from 120 pulses per minute to 60 pulses per minute to reduce the risk of renal injury and increase the degree of stone fragmentation.Alpha-blockers are sometimes prescribed after shock wave lithotripsy to help the pieces of the stone leave the persons body. By relaxing muscles and helping to keep blood vessels open, alpha blockers may relax the ureter muscles to allow the kidney stone fragments to pass. When compared to usual care or placebo treatment, alpha blockers may lead to faster clearing of stones, a reduced need for extra treatment and fewer unwanted effects.
Varicella - Small ulcers on the back of the oral cavity and vesicular lesions on the scalp and trunk are common for Varicella. It is ruled out as the location of the infections are unilateral, unlike herpetic gingivostomatitis which is bilateral. Treatment
The aim of treatment is mostly supportive such as pain control, duration of symptoms, viral shedding and in some cases, preventing outbreak. Antibiotics are rarely prescribed to treat bacterial superinfection of oral lesions. Antiviral drugs are used to treat herpetic gingivostomatitis such as aciclovir, valaciclovir, famciclovir, and in resistance cases foscarnet can be used. Treatment does not prevent recurrence. Most individuals who are immunocompetent will fully recover from recurrent herpes labialis in 7 to 14 days. However treatment with antipyretics, oral anaesthetics and analgesics is often needed. In severe cases of herpetic gingivostomatitis, mouth rinses are useful in relieving oral discomfort. These contain topical anaesthetic agents such as lidocaine and diphenhydramine as well as coating agents such as magnesium-containing antacids. In order to prevent dehydration, oral fluid intake is encouraged. Other treatment options include good oral hygiene and gentle debridement of the mouth. A number of precautions can be taken to reduce the risk of infection of HSV including;

Avoid saliva exchange with those with active HSV
Avoid direct contact with active lesions (if contact occurred, ensure area is washed adequately)
Those with recurrent HSV can apply sunscreen lip balm as ultraviolet light is a stimulus for the infection
