My suggestion would be to go to max panscheel and get the test for hb done, this is also the DGCA official class one center...don't mention that you are a pilot or that you are getting it done just to double check, as max panscheel is not permitted to do that if you have a problem with another center...this is by some weird dgca order....just ask for a regular hb checkup.
If the results are ok, approach vipin sharma, the dgms,then ask him how to proceed to remove the limitation from your certificate, whether he can give you an noc for a re-medical, and what are your options....meanwhile keep up with green leafy veggies and all that.
