My brother-in-law had a small hydrocele. Didn't want surgery. So he looked up hydrocele treatment in ayurveda and found a local vaidya. Simple advice: drink Punarnava kadha, stop eating curd at night, and apply warm castor oil every evening. No expensive meds. No fancy routine. He did this for 6 weeks. Swelling didn't disappear completely, but it shrank. A lot. No more heaviness either. Is it a cure? Not for everyone. But as a natural treatment for hydrocele, it worked for him. If yours is small and not painful, try this before going under the knife. Just talk to a good ayurvedic doctor first. Don't guess.
