Hi, welocme to HCM.
Main symptoms is feeling comfortable in loose cloths. It suggets epididyis or testicle infection. I think you must go for sonography
for exact diagnosis.
Other thing is that stone stucked in penis will cause STRANGURY
, means extreme, untolarable pain while micturating. According to your complaints it is not the stone, so dont worry.
Consult a rediologist as soon as possible.
