<s>[INST] I had A bad reaction from amoxillion and my doctor put me on pretazone for 5days that ended 6 days ago and I am so itchy I want to rip my feet off. Every time I rub on benedrryl it feels better but my feet and my hands and my legs are still swollen. How long before it should go away. [/INST] HI,Welcome to HCM,After stopping amoxicillin..it could take up to 2 weeks for it to fully clear..i advice you to also take an antihistaminic for itching like tab levocetrizine 5mg at night for 7days...get well soon... </s>
