Detailed Answer:
Hello, Thank you for posting your question on HealthcareMagic.
Your dermatologist was right don't go by the percentages on the Internet .
Any drug can give any amount of allergic reaction it depends on how your body reacts.
Since Glucosamine can be made from shell of
shrimps and shell fish the rate of allergic reaction is much more compared to other drugs .
The fact that steroid has helped you only re asses the diagnosis of allergic reaction.
Hope this helps
Best wishes

i ve had a macular rash for 32 days now. everywhere but where my bikini bathing suit covered. It has faded only on chest, shoulders and upper back but remains every where else. I also have EXTREME SKIN MOTTLING on arms/legs. Skin biopsy showed phototoxic cells/sunburned cells and cell death. I have a positive ana, high rf factor, fatigue, excessive thirst, muscle weakness. I got sun exposure while in treatment for Xanax/opiates dependency and was detoxed for about 30 days. I was also taking vistaril, busbar, ibersarten while in treatment. tested for syphilis, hep panel, both non reactive. could this be lupus or even cancer (lymphoma?) Seeing a rheumatologist tomorrow but afraid it may be blood cancer. Am I crazy?
