The top of my foot has been hurting for more than 2 weeks especially when i bend my foot forward. what could it be? what can i do to relieve pain? it is not swollen?

If not allergic take ibuprofen for pain relief. Was there trauma? Are you a runner? Consider x ray to rule out fracture including stress fracture but may be sprain. May consider post op shoe or non weight bearing boot for week or so. If persists consider MRI Follow up with MD

If your pain is not from weight bearing on the foot but stretching soft tissue by pointing foot forward is less likely bone injury . Like any injury the cause or mechanism of action that caused the pain. You did not mention possible cause of pain. Activity? Running? Etc swelling? Exam I believe is required. I would see a podiatrist. If sports related look for knowledgeable sports medicine Dr
