Freaked out!!! (About DH)

So me and my DH have been TTC for a year and a half and having no luck. Waiting to see a specialist.. To make me more crazy today I come home to find out he had to go to the hospital because his left testical was swollen double almost triple it's size! He is now on antibiotics because they think he got stung or bit my a bug and reacted! I don't want to hear any scary stories or anything that's gonna make me worry so please don't post those things. I just really need some support as I'm loosing my mind and terrified it might be worse then they think... I'm so scared!!!
