Dear sir, i am a
kidney transplant patient.Its been more than 7 years after my transplant.I had other urological problems prior to kidney failure neurogenic bladder and reverse influx towards kidney along with some nerves pressed in lower back. So right from my adult hood I resorted to Caverta 50 mg for better erections and good intimate sessions. But as far as i remember i always had a blocked nose,heavy breathing amd increased heartbeat for many hrs.Please suggest a good herbal substititute.
