Testicular pain & swelling. & verecocil!

I have been suffering from testicular pain since a month.So what happened that After masterbating there was developing a slight pain in my right testis.It started around 4 months before & it was happening continuously but there used to pain only after masterbation & then it would disappear after few hours.In the 1st week of April after masterbation the pain got triggered in my right testis & one day later a pain started developing in my abdomen & I started feeling something stiff there in my abdomin & testicular pain too.I went to a local surgeon & he told that my pain was developed due to mosquito bite & prescribed antibiotics.During my medication one day I found swelling,heaviness & severe pain in my testis & little pain developed in my right leg & back later on.But a week ago the pain & the stiffness in my abdomen & swelling in my testis started disappearing.But a little pain in my abdomen & quite swelling in my right testicle is still there.USG report-normal,no hydrocel & verecocil
