Can I go for chest x-ray following got FUE 2 days back?

There is no reason why you would not be able to have an x-ray on your chest after a hair transplant. Just be careful around the transplant area and make sure that nothing rubs against it but that would be the only concern that I could see. 

You can have a chest X-ray anytime after a hair transplant. An FUE is treated just like a regular hair transplant with regard to the recipient area, but the donor area has open wounds which require daily washing with soap and water. Within 3 days of surgery, you can resume full activities, heavy exercises if you wish. The recipient area requires daily washes as well to keep the recipient area free of crusts. I generally recommend and if you washed it properly, there will be no crusts on it, even the very next day. Use of a sponge which we supply our patients, a surgical sponge to fill with soapy water and press on the recipient area daily. By repeating this daily, all crusts can be washed off without any fear of losing grafts. IF any crusts are present, use a Q tip and dip it into soapy water, and roll it on the crusts and that will lift them off without dislodging them, but never rub them, just roll the Q tip on the recipient crust. I like to see no evidence of any crusting in the recipient area and the crusts from the donor area gone in 7-10 days with daily washing.

Post op care: A I don't like the idea of anyone removing grafts that have scabs on them because we have published a paper in a formal medical journal, that when a person pulls off a scab (crust) from a recipient area in less than 12 days, the risk of losing the graft is very high. See the medical paper we wrote in a major journal below in the web reference that proves my point. Everyone having a hair transplant should follow the care I recommend below:
