Post-operative instructions

Pain management

If you are not currently being seen by a pain management physician, Dr. Gregory will provide a prescription for post-operative pain medication, which will be filled at your local pharmacy. Please be advised that not all pharmacies carry pain medication and it is the patients responsibility to find a pharmacy to fill their medications. Please only take the pain medications that Dr. Gregory has prescribed for you. Pain medication can often make you nauseated, and taking it with food can help this substantially. Additionally, pain medication can often make you constipated. A stool softener is recommended to help you feel more comfortable. If you have had regional anesthesia for your surgery, your arm may feel numb and painless after surgery. This is normal. Please begin the pain medication at the first sign of sensation returning, so that you can maintain good pain relief.


For the first 3 days, we recommend that you ice your shoulder or elbow three times a day for 15-20 minutes at a time. It is important to protect her skin with a towel or clothing, rather than placing the ice directly onto your skin. You can continue using ice after the 3-day mark to assist with pain control.


A post-operative appointment will be scheduled once your surgery date is determined. If you have any questions, contact Dr. Gregory's team at 713-486-1700.


You may resume your usual diet following surgery. It is normal to feel nauseated for the first 24-48 hours after surgery as a result of the anesthesia and pain medication. As a result, you may feel more comfortable avoiding heavy, greasy food during this time period.

Wound Care

Dr. Gregory will provide instructions about when you may shower. Generally, you may shower three days after surgery and let water run down the arm. Avoid scrubbing or washing the incision site directly. If you have a clear plastic dressing over your incision, leave this in place while you are showering. If you were placed into a hard splint following surgery, then this needs to be kept completely dry until you are instructed to remove it. You may cover your arm with a trash bag or opt to sponge bathe instead. If you have small battery-operated device coming out of your splint – this is most likely a wound vacuum dressing – please keep this dry and in place until your initial post-op visit.


Please wear your sling or brace as instructed by Dr. Gregory. Please reference your discharge instructions for further guidance. Remove your sling three times a day to move your elbow, wrist, and hand. Avoid moving the shoulder unless instructed.


Please do not drive while on narcotic pain medication (Norco, Oxycodone, Tramadol).


As part of a post-operative pain management plan, you have been provided several prescription medications, as well as an informational handout on how to take the pain medications that were prescribed. This plan is customized based on each patient's individual needs. Generally, you are given a prescription for a narcotic pain medication (Norco, Oxycodone, Tramadol). This medication is effective for post-operative pain relief. Take it as directed. Taking it with food may help with nausea. Other side effects may include drowsiness. Do not drink alcohol while on narcotic pain medication.

Additionally, you were provided with a “shopping list” handout on a stool softener that you may purchase over the counter at the pharmacy (Colace or Senokot). Pain medication can make you constipated, and a stool softener will help relieve this discomfort. Eating fruits and vegetables may also be helpful.

In certain circumstances, you may be prescribed an anti-inflammatory medication (Ibuprofen, Meloxicam, Toradol). These medications help with inflammation and swelling, but can cause irritation to your stomach or GI tract. It is important to take these medications with food to help prevent this. If you have a history of ulcers or GI bleeding, do not take these medications. If you take a prescription blood thinner, you should also avoid these medications.

When to call Dr. Gregory

Please call if you have a fever greater than 101.5, chills, sweats, excessive bleeding requiring multiple dressing changes, foul-smelling drainage, or excruciating pain. During office hours, please call 713-486-1700 to speak with Dr. Gregory's medical assistant. After hours, please call 713-486-1700 or proceed to your local emergency department.
