Can a penis pump cause testicular pain and weak erection?

Hello doctor,

I have been experiencing a mild straining feeling in my left testicle for the past year, although it is not regular. Around ten days ago, I purchased a penis pump for penis enlargement purposes. I used the pump only twice, approximately ten days ago. However, after using the pump, I became concerned about potential injury, so I decided to stop using it five days ago. During that time, I visited a surgeon to address the straining feeling in my testicle. The doctor prescribed Diclofenac for ten days. However, when I started taking the medication, I noticed that my heart rate significantly increased, and I experienced excessive sweating. Furthermore, the pain in my left testicle intensified, and I felt discomfort in the base and ligament of my penis. As a result, my penis became numb, cold, and I began experiencing weak erections. I took Diclofenac only for five days and then returned to the same doctor. This visit occurred approximately five days ago. The doctor then prescribed Cefuroxime 250 mg, but unfortunately, I have not observed any improvement in my symptoms. As of today, which is approximately ten days later, I still experience numbness and slight pain in my entire genital area. Your guidance and assistance would be greatly appreciated, doctor. Thank you.
