Medicines are super cheap in India, except for calcium supplements which are about 8 GBP for 15 tables (you would need one tablet a day).
Sterile gauze will be about 0.60 INR per piece from a pharmacy, but you can get it much cheaper from Amazon. You would go through about 30 pieces of gauze daily.
A curry is about 200-300 INR, bread is about 100, maybe?
An ''alright'' hotel such as the one where Khilo stayed at would be around 3000 INR per day, possibly with breakfast included (depends on your negotiation skills). I personally found a good place for half the cost providing three homemade meals for an extra 700 INR a day.
Uber is cheap... 200-600 INR within central Mumbai.
PT from a physio at the hospital will be around 500-1000 INR, more if they need to come to you and you live far. The most I was charged for a session was 1500, but if you purchase more sessions they should give you a discount.
