<s>[INST] I'm 30 years old, in perfectly good health.  Last week I cut my thumb - stopped the bleeding after maybe 1/2 an hr, cleaned + bandaided it up, change dressing every couple of days and didn't think much about it. Now, 10 days later, the cut seems healed but the area around it appears greenish (no pus) and is numb. Should I see a doctor about this? [/INST] Thanks for posting you query to health care magic. No need to worry as complete healing not take place yet blood  present inside tissue disintegrate and give green discoloration .if you are not having any pain or fever o need to worry . numbness will take long time to releive as damage nerve tissue grow very slowly for which you can take multivitamin tablet.if complaint increases contact to surgical specialist. hope you are satisfied with my answer .  feel free to communicate if any query . regards, Dr.Manish Purohit Infectious disease specialist </s>
