Hi, My Dog Bit My Hand On Friday Night. Since

Hi, my dog bit my hand on Friday night. Since it was the holiday and I didn't want to go to the ER, I opted to go to my PCP tomorrow. My dog bit me and the area between my thumb and pointer finger is now white. Also, the wound is clearly open and might require stitches. My main concern obviously is that my skin is exposed and I take 20 mgs of mtx weekly and xeljanz fir my RA. Is this a serious situation or seems like going tomorrow will help. Thanks
