Swelling in corona glans of penis

[Akkiiey]

I am 25 yr old male
It all started with my massage encounter (body to body massage vaginal flued touched my genitals)
On 24th dec

After few days i saw a cream bump on penis
And after that 2 red bumps on head of penis(corona)
No pain

After few days pain started
Numbness itcyness
Burning sensation
Pain while peeing
And a lot of small bumbs
Like mosquito byted
And fewer for 2 days
My doc said it can be herpes
I tested negative
Igg 0.26 after 5 weeks

Then i visited dermatologist
And he said it is balanopothitis(candidal)

And gave me cream to apply to 10 days

Antifungal for 8 days

Antibiotic for 3 weeks

Now the Thing is
I have relief
BUT
MY CORONA (GLANS OF PENIS IS SWELLED )
DONT KNOW WHY
IT IS NOT LIKE BEFORE
ITS LIKE A EXTRA RUBBER IS INSIDE MY PENIS

PLUS I HAVE RED TIP OF PENIS AND IT HURTS WHILE PEENING

I WANNA KNOW
CAN IT BE 100% CURED?
WHY IS THIS SWELLING ?
MY SKIN IS NOT LIKE BEFORE(GOOD PINK COLOUR)
It is MILD RED COLOURED
?
HOW MUCH TIME IT WILL TAKE ME TO COMPLETELY GO BACK TO NORMAL?

CAN I MASTERBATE?
CAN I HAVE SEX?
THANKS IN ADVANCE
