Trader .. So sorry to hear of your health issues. It seems that mystery ailments keep popping up every day. I've been battling some weird stuff myself for a number of years. The good news is, assuming you make a come-back, you've got at least a decade of good surfing years ahead. I'm 66, and yeah, I got my ass kicked a couple weeks back during a big south swell, but I could see that with more "training", I'll be good for at least a few more years.
I haven't surfed Chicama, but judging from the website below, it's a long, non-threatening type wave. The good thing about such a long wave is that you can choose an uncrowded zone and pick up plenty of waves that others haven't made all the way. As the days go by and you get stronger, you can work your way out the the outside take off zone.
Chicama
Wherever you go, get the paddling muscles ready before your trip. Paddle in the swimming pool if you have to. Pavones (CR) is another very long break (when it's bigger) .. about a kilometer ride. Probably more crowded than Chicama these days, but a pretty laid back atmosphere. Here's a few photos from the beach on a pretty good day:
