Sounds like you had an awesome experience!!
Yeah it might best be to wait on that, I'm not exactly sure how bad a reaction can get if you were bit by a New World T and were more allergic to the venom. NW T's venom is not very potent, symptoms normally involve swelling in the area, numbness, redness in the area, tingling feeling, and that's all the symptoms I know of as far as NW T's go.
Old World T's are definitely the ones you'd rather not get bit by because the symptoms are worse as the venom is much more potent. Though, there have never been any recorded deaths from tarantulas.
