If you are awake during a procedure, you will experience sensation. The injection of the local anesthesia is accompanied by a mild or moderate stinging and burning. This can be lessened by choice of anesthesia mixture and injection technique. After that, the area should be completely numb, but sometimes more anesthesia injection is needed. For a true drooping eyelid "eyelift" (ptosis repair) there is a pinching or pressure sensation as the eyelid lifting muscle is tightened. For upper eyelid skin removal, this is usually not an issue. These sensations are all very well tolerated by the vast majority of patients and should not be cause for significant concern.
Hi Thad1995
It looks like you have lower eyelid retraction, or low position of the lower eyelids. This condition can be seen in thyroid disorders so you should have that checked if the reason for your retraction is not known. This condition can be corrected with lower eyelid surgery. Spacer grafts, or implants surgically placed inside the lids are a common an minimally invasive way to significantly help this problem. Mid-face advancement techniques can be performed in some cases.
If you are taking about 30C dilution of arnica to be taken by mouth, it cannot hurt or help you. This is diluted to 1 part Arnica to 1x10 to 60 power parts water (yes, 1 with 60 zeros). So no actual arnica can be found in an "Arnica" pill. It is just a sugar pill and placebo effect. Check out the research on Homeopathy and how it is supposed to work. Most scientists find it absurd. Enough people seem to believe in it though, that it is a multi billion dollar industry!
