Tip of penis has cracks and swelling.

My penis earlier had dryness . And now  on tip of penis suddenly a month ago -lot of cracks happened and  time swelling too . - i cannot retract the penis as i scream with the cuts and burns and very very  tight and narrow, this was fine before i could retract easily now suddenly extra skin and swelling . -Swelling not decreasing been a month tried coconut oil twice a day. -Zero itching on tip everything fine little to no redness  and no discharge. -But when i retract the cuts and burns and extra skin which i think is swelling because there was less skin earlier. -Such thing never happened to me this is first time . -please explain what is it . How many chances it is curable please.what to do any cream etc . i wish to have normal tip like i had month ago . I dont want to do circumsion
