Hello and thank you for asking HCM. I have read your symptoms and i understand your concerns. I don t think that the infection of your tooth damaged your liver. The liver can be damaged by an infection,but it need to be spread all over the body, (we call it sepsis) and the patient would be in serious conditions and have a lot of other symptoms,like low blood pressure, high fever,polipnea ect,this is not in your case. In your case, the red band in the right side of your stomach that is hot to touch, is probably skin rash that is caused by the varicella zoster virus or cellulitis or some other skin infection. Starting antiviral medicine right away can help your rash heal faster and be less painful and you can use ibuprofen for the pain (for varicella zoster,or antibiotics for cellulitis ex). I suggest you check up with your family doctor to see the red band that you describe,and if its from varicella zoster/cellulitis,he will give you the prescription with antivirals/antibiotics and some pain reviler. If you have any other question,feel free to contact me. Dr.Endri Katro
