PA after BMX?

Ask your surgeon.  Usually you'll be on at least 6 weeks exercise restrictions, and it may be longer depending on your surgeon.

And since you've had a node removed, you are at an increased risk for lymphedema.  You need to start slowly and work up gradually.  I know we're all impatient to get back to our old selves, but pushing too hard too fast can cause permanent long-term issues.  But if you're smart and respect the trauma your body has been through, and work back slowly, there's no reason you can't eventually get back to your old exercise routine.

Here are some guidelines on exercising after node removal:  http://stepup-speakout.org/Handout%20doc%20for%20SUSO-040113.pdf

Good luck!

turquoise-After my BMX, no recon, with lymph nodes(4 on on side & 5 on the other)removed, I was told not to drive for one week. I had my drains removed 6 days following surgery & went hiking the next day. My BS didn't give me any further restrictions. She did not refer me to physical therapy. She told me that studies have shown it didn't make a difference. I know this statement will anger some. I tried swimming 3 weeks post-op & I made 1 lap on that attempt. My 2nd attempt I was able to swim 10 or 15(don't quite remember). My left arm was more sluggish than the right, but swimming helped me get it moving. Swimwear can feel really funny/scratchy & that seems to be what has limited me the most with my swimming. Finding a suit that's comfortable is a chore.

I went back to the gym & started running as soon as my drains came out. At 1st I was careful to isolate certain muscles. I was on my own. I did OK. You might want to ask to see a physical therapist for guidance.
