<s>[INST] Hello I recently went to an adult video store and went into viewing booth. I didn t relize til I left that I had touched the door handle the controls with the hand I used to masterbate. I used spit as lubrication. I did alot research and it s been driving me insane I hear it s nearly impossible because stds die when leaving the body then some say yea it could survive please help! Also I Has swelling on my knuckle went to hospital and they say no way it s an abscess but Thats a sign of STD? They say it s a ganglion cyst but got to days after video store help [/INST] Hello,The ganglion cyst is not related to STD. I suggest using anti inflammatory medications such as Acetaminophen to relieve the inflammation. I also recommend to immobilize the area with a brace or splint. If the ganglion cyst continue you may need to aspirate the ganglion at a doctor's office.Hope I have answered your question. Let me know if I can assist you further.
