Sweeling in testicle. This can be cured?

Hi, I am ram aged 32 and male with height of 5.9. Recently couple of weeks ago I have noticed that swelling on my right testicle and when I consulted an urologist he wrote radiology test and then when I went back to doctor after the results came he told me that "small vericocele" and nothing to worry now and take another test after two months if there is no growth in size of the testicle to cross check what the issue is. I do not have any pain but with my hand touch I can easily feel a slight bubble kind. Why it came and was there any natural treatment for this without operation ? Now I am scared to run and thinking it will become more and with this problem can I continue only walking and is there any medicines to use to get it fixed without any operations ? How this can be cured ? I am single. Please advise and much appreciated.
