Hold the Pickleball, tennis only

That’s actually a very clean experiment, and the result tells us a lot.

The fact that the tendon improved when you stopped pickleball is a strong signal that:

• It’s impact-dominant, wristy, snap-style loading that’s the irritant

• Not general use, not conditioning, and not even tennis per se

Pickleball is sneaky that way—short court, lots of sudden forearm snap, late contact, and quick grip tightening. For a biceps tendon, that’s death by a thousand paper cuts.

Given your constraints (12 sets/week tennis, indoor, non-negotiable)

We don’t try to “rest it more.”

We contain and shape the load so the tendon survives the week and adapts.

Think of tennis as your fixed tax. Everything else must be tendon-neutral or tendon-helpful.

Why tennis is tolerable but pickleball isn’t

This matters for what you change during tennis.

Pickleball

• Short lever

• Wrist-driven

• Late contact

• Constant micro-supination

  
  

  → High biceps tendon irritation

Tennis

• Longer swing

• Earlier contact

• More shoulder + trunk contribution

  
  

  → Load is distributed if technique stays clean

So the goal during tennis is: make every stroke more “tennis-like” and less “pickleball-like.”

Tennis-specific guardrails (these help more than icing)

During play

• Avoid muscling short balls with the arm

• Let balls go rather than reaching late

• On returns: block or chip instead of whipping

Grips & habits

• Slightly relax grip pressure between shots

• Avoid over-supinated forehands when stretched

• Two-handed backhand days are your friend if available

Weekly structure I’d recommend (with 12 sets)

Tennis days

• No other upper-body loading

• Post-play:

  
  

  • 10–15 min ice

  • Light forearm + biceps belly massage (not tendon)

• 
  

• Later that day or evening:

  
  

  • Gentle range-of-motion, no stretching into pain

• 
  

Non-tennis days

You’re already doing this well—just sharpen it:

Option A

• Legs + core

• Light biceps isometrics (pain ≤ 2/10)

Option B

• Swim (kick focus)

• Scapular work (rows with neutral grip, very light)

One important tweak based on your history

Since “whacking” made it worse, I’d pause all fast concentric arm work outside tennis:

• No med-ball throws

• No explosive pulls

• No quick curls

Slow, boring, controlled = healing tendon

Fast, snappy = flare-up

How long to stay off pickleball?

Based on your response:

• Minimum: 2 weeks

• Smarter: 3–4 weeks, then reintroduce at 50% intensity

• First sessions should feel boring, not competitive

If the tendon settles with tennis-only, pickleball becomes a diagnostic tool, not a habit.

Green / Yellow / Red signs

Green

• Morning stiffness <30 min

• No pain spike the day after tennis

Yellow

• Ropey hardness that softens with movement

• Mild ache later in the day

Red

• Night ache

• Pain with simple elbow flexion

• Increasing stiffness despite reduced load

Red = pull back everything but legs and swimming.

Bottom line

You made the right call dropping pickleball.

That improvement wasn’t coincidence—it was causation.

If you want, tell me:

• Is the tenderness closer to the front shoulder groove or lower near the elbow?

• Does serving bother it, or is it mostly groundstrokes?

That will let me fine-tune exactly which tennis patterns to protect.
