<s>[INST] I have had streptococcus in the top of my foot many years ago as a teenager and had always been susceptible to the strep virus. Now as a middle aged adult never get it. Until now, I feel like I may have that symptom again in the top of my foot. and is spreading near the big toe, and am not able to walk well. Its a 30 minute drive to nearest emergency but am not the type to go unless necessary. my question are what are symptoms for this to make sure. I have been fighting a cold for the 1st time in over a year...thank you [/INST] Hi there, Thanks for your query. It is highly unlikely that strep infection was the primary cause of recurrent skin lesion on the foot since teenage. Eczema or allergic lesions (due to contact with an allergen such as synthetic socks, stockings or shoes or environmental allergens), which disrupts the skin, enables bacteria to enter and cause bacterial infection. Other cause can be gout, which too can present in the similar manner. In any case, you need to consult a dermatologist who will examine the foot lesion, reach to the exact cause and prescribe appropriate treatment. in the meanwhile, you may use an ointment containing an antibiotic + a steroid for at least 2 weeks (or more- till the lesion disappears completely), which will take care of lesion, irrespective of the cause. Consult your doctor and apprise him of my opinion. I am certain that he will agree with me and will prescribe the advised drugs in appropriate doses.
