Pumping and edema

[FMLFML85]

I started using a penis pump recently. The erectile tissue where the cylinders are is slow to react and seems to need higher pressures. This comes with alot of edema. The next day after using the pump I still have swelling 12 hours later. IDK if the swelling is completely edema or not. The swelling obviously ads more girth and weight and makes my erections with with implant look more full instead of flat. Another thing is that the tips of the implant are not as far forward for a full day after pumping at high pressures which is great because Ive had 2 revisions for erosion at the tips. Im just worried what kind of damage is being done from the high pressure pumping. Or maybe Im not even experienceing much edema and im experiencing swelling/bruising of the erectile tissue the day after use. Im not getting much nocturnal erections though so maybe the swelling of the erectile tissue is a good thing.

It's fine. Mine does that all the time. Just lymphedema, it eventually subsides if you gave it a rest a few days. I do it regularly because it makes my dick look more like it did pre implant. If you put too high a pressure on it too long you cause more of it so dial it down or shorter sessions and usually you'll figure out the right amount.

I'm amazed you guys feel secure pumping with the implant. You're not worried it'll damage the tubing, cylinders, etc.?

All the indian doctor who does MPP they says the MPP should be cycle after 3months and pumping after 4 months ,i have seen the video

This has been covered extensively on here. a penis pump exerts about 3-5 psi of pressure externally on your penis. Penile implants are rated up to 7500 psi. It's not going to do a damn thing to the device.

I have a Rigicon MPP and was advised not to se a VED after the implant because it was possible to "stretch" the penile tissues and possibly cause a floppy head situation with a MPP

This is a fallacy.

If anything, the partial vacuum produced by a VED will reduce the pressure in the cylinders and the other hydraulics.
The differential pressure between the inside of the corpora and the outside of the tunica is the sum of the absolute pressures, and therefore stretches these tissues more than the outward pressure of the cylinders on its own.

The reason that the pressure inside the cylinders can reduce is that the relatively small vacuum of the VED will stretch the tunica etc. slightly, thereby allowing the cylinders to expand outward slightly.

Because the volume of fluid in the cylinders is fixed, it follows that the pressure will drop slightly.

The only downside to VED use is the risk of oedema in the skin.

For example, let's say that you pump up the cylinders to 80 kPa, then use a VED, pumping it up to 20 kPa of vacuum, which is minus 20 kPa.

The total differential pressure is thus increased to 100 kPa, but the pressure in the cylinders is still nominally 80 kPa.

In practice, because of the very slight additional stretching of the tissues, the pressure in the cylinders may well fall to 79 kPa, making the total differential 99 kPa. Not a lot of difference.

What a VED will also do is tend to pull the cylinders axially outward because of the net pressure acting on the cross-sectional area of the penis.

This apparent lengthening is only illusory and temporary, because with the removal of the partial vacuum, the cylinders will settle back into the crus.

The other danger with a VED is having a ball get sucked up into the VED cylinder.

Very painful!

I appreciate the explanation. I understand the basic physics here. I'm assuming the same is not true for malleables...

Before my malleable implant, I experimented with VEDs. I had a ball get sucked in once, and I panicked. It hurt. So bad.
