Sorry but can’t help on why apart from sounds like a nerve issue as cellulitis is an infection whose effects should be continuous.
The reports I’ve hear up here suggest Curcumin might be useful for nerve issues and joint pain.Some have tried turmeric which is trendy in coffee shops I gather and also more inexpensive in tablet form as Curcumin is the refined active ingredient in turmeric and much more concentrated/ potent.
Might useful to read about Curcumin on the Herbs app or on mskcc website that BCNA recommends.I gather the app is very popular with the medical community too.
Get checked though - am hoping you are getting toward the end of your adjustment to Letrozole and things start lifting a little for you.
