Hi ! Good evening. I am Dr Shareef answering your query. If the hydrocele is getting reduced on lying down, it could be a congenital hydrocele or an inguinal hernia both of which could only be diagnosed by a physical examination. If it is a mild hydrocele, with an anti inflammatory, you might have to go for an antibiotic as well to get a relief which might take about two to three weeks. A good scrotal support would also add to an early improvement. If it turns out to be a hernia, this has to be assessed by a general surgeon in your area followed possibly with an operation. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
