Yes, indeed you can however try to keep distance between yourself and sick people especially hospitals prior to going and whilst you are there as colchicine reduces your immunity capabilities.
One thing I would like to ask is have your attacks become less intense since starting allopurinol 6 months ago or are they still the same on the pain scale? If they are getting less painful allopurinol is indeed working and your crystals are getting less and less. If they are not however then you are still going through the primary stages of debulking.
