Hi, thanks for posting your query to us.
As you have mentioned, it seems that itching and rashes are due to gestone
Tenderness, pain , swelling , redness at the injection site is quiet common and occurs in almost every person, severe itching
and rashes all over the body can occur with gestone (oral or intramuscular)though not very common.
Since the tendency and frequency of rashes has decreased, it means that the effect of gestone is waning off slowly and you will be completely normal in a month or two.
You may take an anti histamine
daily for 15-20 days for itching.
-Apply local steroid cream over the red areas.
-A soothing lotion like calamine
lotion will help.
-You may even take a short course of oral steroids
for early recovery. You may consult your doctor for the same.
In your next IVF you avoid taking gestone.
Wish you a speedy recovery.
