Noticed Itchy Rashes On Inner Elbow. How To Get Rid Of These Rashes?
I do tend to agree with your husband based on the history you have provided...not the poison oak but some sort of allergic contact dermatitis aggravated by light.
What you would greatly benefit from is a topical cortisone cream eg betamethasone or hydrocortisone that you should be able to aquire over the counter applied twice/daily for 3-5 days together with fexofenadine 180 mg a non-sedative antihistamine taken orally once/daily.
This should rid you of the problem. Scabies is a touch far fetched but not an impossible entity but this is not the 'classical' presentation. Still, if no respte in 3-5 days, you may want to attempt to try a cream called 5% Permethrin which may require you to visit your GP for a prescrption.
Cheers & Good Luck!
