since applying tea tree oil (100% on a few cuts- did not know to dilute- and never have in the past ten years of use with no issues) I have developed terrible a rash which has blistered. saw an NP one day ago who prescribed prednisone and keflex. My concern is the location (forearm above wrist so close to joints, tendons, etc). I have NO health insurance so visiting the NP was costly and she did not explain anything to me or even tell me a diagnosis and had one foot out the door in the five minute visit. I assume is cellulitis but am told I should have received parenteral antibiotics (injection) and bloodwork done among other things. any suggestions? would i best be served in the er? Has any of you ever had something like this due to tea tree oil use? Thank you in advance. Any insight would be helpful and appreciated.
