Last Night It Was A Nightmare For Me , As

Last Night it was a nightmare for me , as my balls were itching and i scratched them ..afterwards i applied Betadine (Providone-iodine)5% , Today morning ...the itching started on the other side of the ball ..This time it was uncontrollable ... For about 1 hour it a maddening experiance as i literaaly in unbearble pain as I was scratching and resulting in red tender skin with cuts in that area.. With no one at Home.. (my wife being a prof attends morning college was out) as suggested in an article on the net I mixed one part white vinigar with three parts of water and applied with a cotton ball. Though my balls were in fire for about 5 minutes after that i got some relief.. Later again consulting the net i told my 82yera old father to go to the local medicine shop and buy caladryl lotion.. Which I applied.. I thought it would be soothing ..but on the contrary it was a extreme torture on the sensitive area as the area was in flames ..Fo the next 3 hours ,i was wriggling in pain.. sweating profusely ... after 3 hours it subsided though i still have aburning sensation..but the itching has been gone.. What will I do now .. Nb'' forgot to mention that there was no symptom other than itching in the first fw hours of the problem..but now the area is swollen and reddish in colour... ..What will I do now ...Pls help doctor..
