Problem in testicles (light feeling)

I was hit by a metallic water bottle on my right testicle.After few week time the area became stiff and swelled.took many medicines and the problem was gone.Within this time i went for USG reported no problem in right side but varicocele on left side(subclinical)..At the start of this year in january 2017 i used to feel some kind of movement within the testicle and other parts of it..probably it was due to infection acc to what doctors reported..I was given antibiotics such as Levoflox(500 mg) after that Amoxyclav(625 mg) after that finally Doxycyline(100 mg)..After the course of medicine i dnt knw whether any sideeffect took place.My both testis rght mjrly have become tender,weightless light,they feel hollow and sometimes they shrink.As if they are completely no more in scrotum.The weightless feeling is very pathetic i cnt even sit,rest or do any other task efficiently.gone for CLr doppler reported grade 3varicocele and no prb on right.Bt m fcing this problem in bth testis,mjrly rght
