The decrease in pain and swelling is a good sign.
Good Day and thank you for being with Healthcare Magic!
It is a good sign that the swelling in your testicles and epidiymis are going down meaning that the inflammation and damage because of the trauma (sitting down on it) are healing properly. Did the ER get a urinalysis
to check for urine infection? Often times the swelling can be because of an infection and it is already swollen prior to you sitting down on it.
My general advice : 1) refrain from any physical strenous activity (including sexual contact and ejaculation ) until all the swelling and pain resolves. 2) Wear tight fitting underwear to limit testicular movement and prevent further inflammation also until pain resolves and 3) continue anti-inflammatory and pain reliever prescribed to you to decrease pain and swelling. If the pain and swelling worsens I would suggest a testicular ultrasound
to properly assess if there is testicular damage and to further plan the necessary treatment.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.HealthcareMagic.com/doctors/dr-manuel-c-see-iv/66014 I would gladly help you. Best wishes.
