<s>[INST] hi there, i have an insect bite to the back of my upper thigh. i got it last friday and it is still very itchy/sore and has risen considerably and spread to around the size of a big orange in circumference. what should i do about it? i have been using anthisan cream so far. [/INST] HI, thanks for using Chat Doctor The fact that it is still itchy would imply that you are still having an allergic response. You may need to consider the use of a mild steroid cream to help reduce the inflammation. This can be used for a few days, if the rash is only allergic, this would help. In some cases, an infection can occur as a result of the introduction of bacteria due to the scratching. If this happens, the use of a topical antibiotic would also be needed. I hope this helps </s>
