Is this a possible reason for my problem? If so, what should I do? Anything you can think of tell me (Photo)

Im an 18 year old male, was given Isoface for treatment for the acne. I started last week, and take it twice a week. I have been feeling since two days ago my scalp to hurt, itchiness, and burning sensation. It even hurts without touching it! I asked my mom yesterday to see if my scalp was red or anything and she said it looked normal to her. It also seems to be that it hurts for as the day goes pass by. Thank you and help me please!, ps the shampoo that I use is yellow Selsun (just in case)
