It seems scarpe which you had, not yet healed completely so you are facing with pain. Take some over the counter anti infllamatory tablets (Panadol: paracetamol
). Do hot water fomentation and apply anti inflammatory gel such as deep heat ointment. Do not start running immediately but give few more days for that wound to heal completely. As you are not having fever
, chance of infection is ruled out. Red ring is there as it is healing it will fade after few more days.
