For two months, aching pressure pains on top of head, both left and right but mainly left side. tingling/crawling sensation on top of head. started having night sweats occasionally, concerned about brain tumour?

Unlikely Brain tumor: Brain tumors are uncommon in your age group, so I do not think that is the cause of your head pressure. Common cause of such pressure is tension from stress. If the headaches is getting worse every week, then in 4-6 weeks you can decide whether you need to see your doctor for checking your brain. For now try relaxation exercises like daily walk and mediation/ breathing exercises.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
