My 20 yr old son is experiencing severe pain in his groin area as well as his leg. He has had this before and I think he was advised to take allergy meds. Doctors claimed he was allergic to dogs and he took meds and seemed to be okay. 3 years later (he has been around dogs these past few years) this pain has returned. Side note- he cut his cornea last year taking his contacts out, Serious infection and 3 specialists (including Duke Eye Center) have not figured out why he is not healing- Last explanation was that our son could have herpes. Any idea on how we should approach treatment?
