It seems your neck is a bit swollen but you are not feeling any pain. This could be caused by an infection or a swollen gland. Sometimes, it can occur without any serious reasons as well. However, the priority is to have a doctor take a look at it to be on the safe side. They may have to conduct some tests to be able to tell what is going on. 

Your scalp problem could be a medical issue that requires medical treatment. I recommend you should pay a visit to a dermatologist, who is a skin expert. They can detect the condition and recommend the medications or treatment option that should be taken. Avoid using any harsh chemicals on your scalp until you have been to a doctor.
 

Face proble­ms arise frequently. They occur whe­n pores clog with oil and dirt. Blocked pores me­an red bumps form. Or blackheads. Or whitehe­ads appear. Washing your face gently twice­ daily helps reduce the­se issues. Use mild cle­ansers. Don't overly touch your face. 

You could get relieved by itching, red spots, and peeling sometimes. Switching your soap might help, but as neem doesn't work for you, let's find some alternative. Seek for soaps endowed with the elements such as tea tree or coconut oil. There is a chance that these can aid in the combat against the fungus without the risk of your skin looking dehydrated. To add, be cautious enough to rinse thoroughly and pat the skin dry after the application of the soap.
