<s>[INST] There a bite, or what seems like a spider bite on my arm that occured a few weeks ago. it started to form a yellowish kinda pus so i poked it open with a toothpick. the yellowish pus came out as well as blood so I tried to squeeze out as much pus out and cleaned it with a tissue paper. However the pus kept forming again so I opened the wound again to clean it. The wound has yet to heal and I am wondering if I need to go to the doctor to have it checked out or should I do something else or wait for it to heal? [/INST] Hello, Welcome to Chat Doctor, I can understand your concern for insect bite. After reading your query it appears that you have developed insect bite hypersensitivity. This basically caused by hypersensitivity to the insect bite which can cause acute aggravation of the problem and flare up of the lesions. Thank you. As you are not getting relief from the steroids an antihistamine, so I suggest you to meet a dermatologist and get your skin examined to get proper best treatment. You can apply steroid creams of higher potency for the early resolution of the lesions. You can take oral anti histamine like loratadine or levocetrizine under medial advice. If you have pain and irritation then you can take a tablet paracetamol or diclofenac. Do not scratch or rub the skin as it can lead to further aggravation. Despite above measures if the problem is not getting better than it is better to consult a dermatologist for best guidance. </s>
