I am not an expert but just a thought that the reaction to oil might actually be a die off symptom. you can also try some Yoga in conjunction with your diat and medication? AMong the ones i have seen, this one here is authentic.
The actual postures start after 10 minutes into the video
Again the rule is.. Listen to your body. Only perform within limits. and if any posture proves counter productive, stop.
Hope you get well soon
God Bless All!
