Blocked nose, clear mucas (loads of it), headache and aches.. not sure what tablets i should take to help?

Sinusitis: The symptoms you describe may be from sinusitis (this is likely viral, although it could be bacterial). You can try nasal saline sprays and warm compresses to your face to help relieve the infection. Over-the-counter sinus medicine, like Sudafed can help with your sinus pain. If you don't find relief in 2-3 days, or if you develop a fever, then see your doctor. Best wishes.
