I have a torn big toe joint capsule and did prp 10 weeks ago. stil not healed. can i deep tissue masage it and take comfrey (anti-inflam?) and silica?

Why prp : I don't believe prp is FDA approved for this type of injury. Please ask you doctor. Capsule injury usually heal after 21 days of immobilization

Immoblize: for this to heal you should wear a fracture shoe to prevent bending in the joint. 2-4 weeks to heal. If not ....get an X-ray to rule out other problem and get a dianosis

Not regulated: Will defer to MDs on torn capsule, but so far, research suggests that Comfrey does not provide sufficient health benefits to justify risks, which include liver damage, cancer, and possibly death. Silica may be harmless, but the beads are sometimes doped with cobalt chloride, which is toxic. Recall that supplements are not FDA regulated, so purity and quality are not guaranteed. Be careful.
