Hi Doctor, When I was round about 13years of age I had an operation(fixation) of the left testicle. This was after I had experienced pain in the left testicle, the family took me to specialist doctor who said this was due to the fact I had big testicles that cause discomfort and at times I usually sit on them or they are squashed between my legs so it caused something to twist inside there such that blood no longer flows to the testicles so they hurt and my lead to a condition that he called tortion if i that operation was done on my left testicle. The operation was done and the pain disappeared for a while now i m 24years of age and I feel pain in the same testicle occasionally, it can go on for like four days and back to normal then it happens again repeatedly, I feel as if the pain gets worse every time it happens. Recently a friend mentioned to me during a conversation that menthol cigarettes can affect your testis if smoked for a while and i smoke heavy as it is already(I have been smoking since 2012 already) so I need to know if this is being caused by cigarettes or it s the previous problem repeating itself. Do I need to see a doctor for this or it will be normal after a while, i m really worried, please help
